A vehicular cooling device includes a heat medium circuit, a waste heat supply device, a heat exchanger, and a heater. A heat medium circulates in the heat medium circuit. The waste heat supply device is configured to generate a waste heat in accordance with operation of the waste heat supply device and supply the waste heat to the heat medium. The heat exchanger is configured to exchange heat between the heat medium and a lubricant lubricating a transmission of a vehicle. The heater is configured to heat the lubricant that is inside the heat exchanger. According to this vehicular cooling device, since the heater heats the lubricant, the transmission can be warmed up early, and thereby friction in the transmission decreases to improve fuel economy.

Vehicular cooling device

A webbing retractor wherein a take-up shaft supporting a webbing worn by a seat occupant of a vehicle is rotated in a webbing taking-up direction by an urging force of a take-up mechanism connected to the take-up shaft. The rotation of the take-up shaft in a webbing drawing-out direction is stopped upon detection of a predetermined acceleration of the vehicle, whereupon the take-up shaft is moved by the webbing drawing-out force to lock an intermediate portion of the webbing drawn out from the take-up shaft. The take-up shaft and the take-up mechanism are connected together via a pair of mutually meshing gears. One of the gears is moved together with the take-up shaft in a state in which its engagement with the other gear is maintained when the take-up shaft is moved. Accordingly, the take-up mechansim is not moved when the take-up shaft is moved.

Webbing retractor

A webbing drive apparatus for an automatic seat belt apparatus in which a webbing is automatically fitted around an occupant by driving one end of the webbing which comprises a screw plate with which one end of a wire for driving the webbing is engaged and which has portions for contact with a drum so as to be rotated through the contact portions by the rotational force of the drum. It is as well as moved in the direction of the rotational axis of the drum, whereby the wire is spirally wound around the drum. Each of the contact portions have a bent portion which is bent substantially at right angles with respect to the rotational direction of the drum. The rotational force of the drum is therefore transmitted to the screw plate through these bent portions.

Webbing drive apparatus for automatic seat belt apparatus

In an assistant apparatus for fastening a webbing, which is adapted to move an intermediate portion of a webbing in the front direction of a vehicle for aiding an occupant of the vehicle in fastening the webbing around the occupant, a reach arm is provided which supports the webbing passing through the reach arm. The reach arm is capable of being swung in the front and rear directions of the vehicle and is always urged in the front direction by a return spring. The reach arm can be held in a rearward position by a cam engaging therewith, the cam being disengaged by a solenoid when the solenoid is energized. Therefore, a complicated gearing mechanism is unnecessary for driving the reach arm.

Assistant apparatus for fastening a webbing

An acceleration sensor for detecting acceleration of at least predetermined magnitude. The sensor has a first lever capable of swinging when acceleration of at least predetermined magnitude occurs, and a second lever capable of swinging to come into contact with the first lever when vertical acceleration of at least predetermined magnitude occurs so as to limit the swinging of the first lever. Therefore, the first lever is prevented from swinging when vertical acceleration of at least predetermined magnitude occurs.

Acceleration sensor

A driving-force transmitting structure applied to an automatic seat belt apparatus having a slide piece moved along a guide rail by a driving force and a slider adapted for supporting a webbing for restraining an occupant, the slider being capable of moving in response to the movement of the slide piece so as to apply the webbing around an occupant. This driving-force transmitting structure is adapted to transmit the driving force from the slide piece to the slider. The slide piece and the slider overlap each other. The slider is provided with opposed surfaces which face end surfaces of the slide piece facing in the direction of movement of the slide piece.

Driving force transmitting structure for automatic seat belt apparatus

An apparatus for driving an intermediate portion of a webbing for use in a seatbelt system for restraining an occupant of a vehicle by means of a webbing having one end accommodated in a webbing accommodating device through a biasing force is arranged to withdraw the webbing from the accommodating device in opposition to the biasing force. Accordingly, when an occupant is to apply the webbing to himself by withdrawing it from the accommodating device, the webbing can be withdrawn and applied with a small manual force.

Apparatus for driving an intermediate portion of webbing

A webbing driving device which is capable of maintaining a constant gap or space between a wire and a sheet around the periphery of a drum. The webbing driving device includes a rotatable drum, a screw plate to which the wire is connected and is movable in the axial direction of the drum when rotated together with the drum, a wire driver for winding the wire around the drum in helical fashion, a first sloping surface formed on the screw plate parallel to the direction in which the wire is wound around the drum so as to define one end of the wire winding area and a second sloping surface formed parallel to the direction the wire is wound around the drum so as to define the other end of the wire winding area. The gap is formed by the first and second sloping surfaces. The gap between the wire and the two sloped surfaces is constant around the periphery of the drum, and the gap between the wire and the sheet can be set to a constant value around the periphery of the drum.

Webbing driving device for use in seat belt apparatus

Disclosed is an automatic seatbelt apparatus which is capable of automatically applying, or canceling the application of, a webbing around an occupant of a vehicle, wherein a limit switch for detecting that a slider, which guides the webbing along a guide rail between a stopping position on the forward side and a stopping position on the rearward side of the vehicle, has arrived at the stopping position on the forward side of the vehicle is disposed in such a manner as not to hamper any further movement of the slider toward the front of the vehicle. Accordingly, the stopping position of the slider on the rearward side of the vehicle can be changed regardless of the stopping position at which the slider is located.

Automatic seatbelt apparatus

An apparatus for reducing webbing wind-up force has a ratchet which rotates together with a take-up shaft for winding up a webbing, a rocker arm with a pawl engageable with the ratchet, a bidirectional solenoid for causing the rocker arm to pivot, and a snap action spring. When an occupant has the webbing fastened, the bidirectional solenoid is activated for a predetermined period of time so that the pawl is engaged with the ratchet, and thereafter, the rocker arm is held in its engagement position by the action of the snap action spring. When the occupant unfastens the webbing, the bidirectional solenoid is activated for a predetermined period of time in the direction opposite to that in the above operation so that the pawl is disengaged from the ratchet, and thereafter, the rocker arm is held in its disengagement position by the action for the snap action spring. Thus, it is possible to reduce the amount of electric power consumed by the bidirectional solenoid.

Apparatus for reducing webbing wind-up force

A seatbelt system for a vehicle which enables a webbing to be automatically fastened to the body of an occupant includes a tape subjected to driving force derived from a motor. The distal end portion of the tape is provided with a plurality of neck portions. Projecting members are provided on a slider which retains the webbing. The projecting members are fitted into the neck portions, respectively, so that the driving force from the motor is transmitted to the slider while being distributed among a plurality of portions of the tape. Thus, even when the tape has a relatively small width, the driving force is reliably transmitted to the slider and hence the webbing.

Driving force transmitting structure for automatic seatbelt system

Disclosed is an automatic seatbelt apparatus which is capable of automatically applying, or canceling the application of, a webbing around an applicant of a vehicle as a slider to which one end of the webbing is retained along a guide rail disposed in the vicinity of the roof of the vehicle is moved in the longitudinal direction of the vehicle via a flexible elongated member driven by the driving force of a driving means. A switch, when located in its webbing-application position, is adapted to stop a motor by detecting the application of the webbing and is so disposed at this time as to be capable of moving in accordance with the bending of a flexible guide member. Accordingly, since the switch can be moved when the guide member bends, the webbing-application position can be altered even in the webbing-applied state.

A controller for automatically effecting disengagement of a buckle device includes a moving means which moves a lock plate engaged with a tongue plate. When a predetermined period of time has elapsed after the acceleration acting on the vehicle exceeds a predetermined value, the controller controls the moving means such that the tongue plate and the lock plate are automatically disengaged from each other. It is possible to automatically disengage the tongue plate from the buckle device in an emergency situation, such as collision or overturn, of the vehicle.

An apparatus for driving a wire for actuating a webbing of an automatic seatbelt system includes a guide member and guide means. The guide member is prevented from rotating relative to a rotary drum on which the wire is wound, but allowed to move in the axial direction of the drum. One end of the wire is retained by the guide member, and this guide member is moved in response to the rotation of the rotary drum by the action of the guide means. Accordingly, the wire is tightly or closely wound on the rotary drum at all times.

Webbing driving apparatus

A webbing retractor has a take-up shaft for winding up a webbing. The take-up shaft is biased in the direction in which the webbing is wound up, by a spring having such a biasing force that there is no slack in the webbing when it is wound and yet the occupant feels no pressure from the webbing when he has the webbing fastened. When the webbing is unfastened and wound up onto the take-up shaft, a motor is activated, and the rotational force thereof is transmitted to the take-up shaft through a centrifugal clutch so that the take-up shaft is rotated, winding up the webbing.
