In a webbing guide structure, when a take-up stopper has made abutted to a contact face of a webbing guide due to take-up force acting on a webbing arising from a spiral spring of a webbing take-up device, a rigid portion of the webbing extends out from the webbing guide towards the vehicle front-side, and a portion of the rigid portion further towards an tip end than the take-up stopper projects out from the rear seat back to the vehicle front-side. Due to utilizing biasing force of the spiral spring to project the rigid portion out from the rear seat back to the vehicle front-side, the need to provide a separate mechanism to project the rigid portion out can accordingly be eliminated. A gap between the rear seat back and the webbing can thereby be provided by employing a simple structure.

A seat belt apparatus simplifying an operation of mounting tongues to left and right respective buckles is provided. In the seat belt apparatus, a second tongue is held by a second tongue containing portion provided at a first buckle, and a first tongue is held by a first tongue containing portion provided at a second buckle. When mounting a first and second shoulder belt, and a first and second lap belt, when both of the first buckle and the second buckle are pulled to a front side of an occupant and an inserting hole of the first buckle and an inserting piece of the first tongue are opposed to each other, an inserting piece of the second tongue and an inserting hole of the second buckle are opposed to each other. When the inserting piece of the first tongue is inserted to the inserting hole of the first buckle, the inserting piece of the second tongue is inserted to the inserting hole of the second buckle.

A buckle pretensioner system includes a substantially L-shaped rail for guiding a buckle body of a buckle from a position where the buckle body engages with a tongue plate to a position corresponding to a lumbar region of a vehicle occupant. When a vehicle disposed with the buckle pretensioner system undergoes a sudden deceleration, a piston inside a cylinder is moved in a frontward direction of the vehicle by gas generated by the actuation of a gas generator, a buckle stay is pulled by a wire coupled to the piston, and the buckle stay is moved along the shape of the rail. As a result, the buckle body supported by the buckle stay pivots from the position where the buckle body engages with the tongue plate to a vehicle occupant restraining position of a webbing belt, and then is pulled to the lumbar region-corresponding position.

A child seat is an International Standard-compliant CRS. The CRS has right and left-side fastening attachments that are spaced from each other by a predetermined interval in a direction of a width of the CRS. CRS switch mechanisms are disposed at sites in a seat cushion at which anchor bars are disposed. At least one of the CRS mechanisms has a key cylinder. By turning the key cylinder through the use of an ignition key, a CRS detection switch can be switched between an ON state and an OFF state.

A preloader for a webbing retractor, having a safety device which can be selectively switched to one of an operative state in which a sensor, which detects the state of rapid deceleration of a vehicle, is brought to a non-detecting state, and an operation-released state in which the sensor is brought to a detecting state. The safety device, when in the operative state, interferes with a vehicle component to be mounted after installation of the webbing retractor to a vehicle body and prevents the vehicle component from being mounted to the vehicle body and allows, when in the operation-released state, the mounting of the vehicle component to the vehicle body. Accordingly, an operator can easily determine whether the safety device is in the operative state or in the operation-released state.

A collision sensing system for a side air bag system has a door opening state detector and an air bag actuation inhibiter. The side air bag system is provided with an air bag which is confined in a side door of a vehicle and inflated and expanded in a space between an occupant of the vehicle and the inner side wall of the compartment such as the side door when a collision detector detects a vehicle collision. The air bag actuation inhibiter inhibits the inflation of the air bag when the door opening state detector detects the open state of the side door.

Collision sensing system for side air bag system

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.

An overlock prevention mechanism for a vehicle acceleration sensor used on a retractor for a seat belt device in a vehicle comprises an inertial body which moves in response to acceleration of the vehicle; a sensor casing on which the inertial body is mounted; a ratchet wheel which locks the retractor; and a composite sensor arm assembly comprising an upper sensor arm which is adapted to be engaged with the ratchet wheel and a lower sensor arm which is adapted to come into contact with the inertial body to transmit the movement of the inertial body to the upper sensor arm; and when the upper sensor arm is interlocked with the ratchet wheel, the lower sensor arm is forced toward the inertial body by a force activated from the ratchet wheel and transmitted through the upper sensor arm, so that the inertial body is pressed to the sensor casing against movement.

A reclining angle adjustment device includes a brake mechanism mounted on a control handle shaft for transmitting angular movement of a control handle to an angularly movable shaft, a stopper arm rotatably mounted on the angularly movable shaft and angularly movable by a driven member of a transmission mechanism, and stoppers for limiting angular movement of the stopper arm to determine a range of fine reclining angle adjustment.

Reclining angle adjustment device

A seat back reclining mechanism for a vehicle seat includes an upper and lower brackets respectively secured to the seat back and the seat cushion. A reduction gear mechanism is provided between the upper and lower brackets for a stepless adjustment of the reclining angle. An actuating knob is located at one side of the seat cushion for the convenience of operation. A belt-sprocket type motion transmitting mechanism is provided between the actuating knob and the reduction gear mechanism for transmitting a rotation of the knob to the gear mechanism. In order to prevent the seat back from being inclined under the load applied by the passenger, a constraining device is provided for preventing the motion transmitting mechanism from transmitting the force from the reduction gear mechanism.
