A seat frame for a framework structure of a vehicle seat includes a plurality of frame bodies formed by bending a single tubular member. The single tubular member is formed in a closed cross-sectional shape by a single long and flat member being bent in a direction that is at a right angle with respect to the lengthwise direction of the long and flat member, and then end edges of the tubular member that have come to face each other being joined together by welding. Each of the plurality of frame bodies includes a bend part and rectilinear parts. The bend part is rectangular in cross section. The rectilinear parts include a rectangular cross section portion and a cross-section-varying portion. The end part of the cross-section-varying portion, connected to the rectangular cross section portion, is rectangular in cross section.

Seat frame, and method for manufacturing seat frame

A seat for vehicles including a seat cushion, a seat back, and a head rest has the following arrangement to ensure that a surface member can be relatively easily but positively removed from a urethane pad if a foam molding defect is found in the urethane pad in integral molding of the urethane pad and the surface member. In the seat for vehicles, any one of the seat cushion, seat back, and head rest has a configuration where a surface of the urethane pad is covered with the surface member. The urethane pad and the surface member are partially bonded together by integral molding.

Seat for vehicles

A plate is continuously press-bent, into a shaped member having a recess opening at one surface (i.e., lower surface). Then, the plate is bent back by pressing, at the front and rear ends, covering the openings of the recess and a side frame having open cross sections, each with a gap, is thereby formed. In the forming step, the side frame is not welded and has open cross sections, each with a gap. The side frames are then subjected to the next step (i.e., step of assembling the seat frame). In the step of assembling the seat frame, the side frames and coupling members are welded together, constituting a substantially rectangular seat frame. As the side frames are so welded in step of assembling the seat frame, a rigid structure each having closed cross sections with no gaps is formed.

Method of forming a seat frame of a vehicle seat, seat frame for use in vehicle seat, and vehicle seat having the seat frame

In a rear seat having a configuration which, in the state that a seat cushion is folded forward with a seat back flattened on the seat cushion side, makes an upward back surface of the seat back become almost the same height with a floor surface of a cargo room, to avoid giving a restriction and hurt in amenity to a passenger seated on the seat cushion in the space on which feet of are put, the present invention provides a vehicle seat to which parallel link mechanism portions are equipped that connect the seat cushion to a floor surface under the seat cushion of the vehicle, and a mechanism is provided to fold the seat cushion forward with the posture of the seat back held by the parallel link mechanisms in the state that the seat back is flattened to the seat cushion side.

A vibration detection device () is provided with a vibration detection unit (), a sensor-side leak determination unit (), a first transmission unit (), and a second transmission unit (). The vibration detection unit () detects vibration transmitted through piping (). The sensor-side leak determination unit () determines whether or not there is a possibility of a leak in the piping () based on a measurement result of the vibration detection unit (). When the sensor-side leak determination unit () determines that there is a possibility of a leak, the first transmission unit () transmits provisional leak information to an information processing device (). The provisional leak information indicates that there is a possibility of a leak in the piping (). When waveform request information indicating a request for waveform data of the vibration is received from the information processing device (), the second transmission unit () transmits waveform data measured by the vibration detection unit () to the information processing device ().

Leak detection system, vibration detection device, information processing device, and leak detection method

A signal acquisition unit () acquires a signal. From the signal acquired by the signal acquisition unit (), a detection signal extraction unit () extracts, as a detection signal, a signal of any frequency band among a plurality of partial detection frequency bands into which the frequency band that is the subject of detection has been divided. A determination unit () determines, in order, for each detection signal corresponding to each of the different partial detection frequency bands, whether the detection signal shows any leakage, and if at least a prescribed number of the detection signals are not showing any leakage, determines that leakage is not taking place.

Leak-detection device, program, and control method

A pulley adapted to be press-fit on a driving shaft has projections having vertex portions with flat surfaces formed on an inner peripheral surface which is defined by a center hole of the pulley. The flat surfaces of the projections make pressing contact with an outer peripheral surface of the driving shaft at a band-shaped contact area (or surface) extending spirally or concentrically along a longitudinal direction of the pulley.

Pulley and press-fit pulley structure

This invention relates to a wire bonding gold line used for connecting a semiconductor tip electrode with an outside lead portion. This gold wire characteristically contains gold (Au) having a purity level 99.996-99.9995 wt % and 0.0032-0.008 wt % by total weight of said gold wire of germanium (Ge) so that the electric resistance of the wire bonding gold line is reduced, while the mechanical strength such as tensile strength and high temperature strength is excellent and a gold ball can be shaped into the form of a nearly perfect sphere in the connection of the tip electrode.
