A power seat slide apparatus includes: a housing fixedly mounted on the first rail and possessing a reverse U-shaped cross section projecting upwardly with an upper wall, which forms an upper surface of the reverse U-shaped cross section, and first and second sidewalls, which forms side surfaces of the reverse U-shaped cross section. The housing further includes a notch defined by a first notch end surface of the upper wall and a second notch end surface of the first and second sidewalls. A nut ...

An adjustment device is provided for adjusting the height of a side cheek (1) of a seat, whereby the side cheek (1) has a compressible section. The adjustment device comprises pressure means (3) allocated to the compressible section, which are designed in such a way that in a first state they exert a compression pressure on the compressible section, and that in a second state they do not exert any compression pressure on the compressible section. With a device of this kind, a simple height adjus...

A vehicle seat includes a subframe arranged to be secured to the vehicle or and an upper frame mounted on the subframe by four pivotal levers to form two pairs of parallelogram linkages and so constrain movement of the upper frame relative to the lower frame along an arcuate path. A pair of mounting plates carrying a back rest are pivotally secured to opposite sides of the upper frame. A pair of control levers couple the mounting plates to respective levers in a manner such that when the mountin...

Disclosed is a bracket angle adjustment mechanism which includes external-tooth and internal-tooth gears having improved tooth shapes allowing an operating force for rotating a control shaft to be reduced. In the bracket angle adjustment mechanism, each of external teeth (14b) of the external-tooth gear 14 has a half-round shape having a center defined by a single point "a" on a reference circle PC (14), in a region of an addendum T1 between the reference circle PC (14) and a tip circle AC (14),...

A shock and energy dissipating device includes a number of cylinders attached to an outer peripheral portion of the vehicle for being actuated when a force is applied onto the outer peripheral portion of the vehicle or when a collision happened to the vehicle. A seat device includes a base seat member, a base support for attaching to a bottom of the vehicle, an upper support for attaching to the base seat member and a moving device disposed between the base support and the upper support and coup...

A recline adjustment apparatus locatable on a vehicle seat to control a recline angle of a rearwardly-facing child car seat relative to the vehicle seat. The apparatus includes a cover to be placed on the vehicle seat. The apparatus further includes a recline adjuster. The recline adjuster also includes a plurality of height creation pockets coupled to the cover, and a plurality of bolsters sized to be inserted into and removed from respective ones of the height creation pockets. The height crea...

A seat component of an adjustable seat, particularly of a motor vehicle seat, is mounted on a base component for movement generally in the forward and rearward direction of the seat. A toothed rack is rigidly mounted on the seat component, and a pinion member is mounted on a driving shaft and meshes with the toothed rack. A driving element of a disk-shaped configuration is rigidly connected to the driving shaft and has a plurality of circumferentially distributed openings which receive correspon...

The device comprises a stationary bottom frame, a vertically movable top frame urged upwards by a compression spring, and scissors-type guiding levers between the top and bottom frames. One end of the spring is applied against the guiding levers and the other end is applied against a screw-and-nut system for adjusting flexibility of the suspension according to the weight of the user. A screw or a toothed rack are provided for adjusting the useful vertical range of travel of the suspension accord...

A vehicle passenger seat with an upholstery cover having a fabric seam designed to absorb energy from a seat occupant upon impact. Means for progressively absorbing energy from the seat belt occupant are disclosed. Use of the fabric seam to absorb vehicle passenger seat occupant energy increases the survivability of an impact for an occupant of a seat with a separate inner and outer seat frame, and relates to compliance with energy absorption requirements for seat-backs of 49 C.F.R. Section 571....

A vehicle seat or seat portion including a frame, a central cushion defining a seating surface attached to the frame and a bolster connected to the frame. The bolster is moveable between a first retracted position and at least one second extended position relative to the central cushion. The vehicle seat also includes an actuator coupled to the bolster to move the bolster between the first retracted position and at least one second position.
