A drive member including a motor with a longitudinal axis and with at an actuating end a gear mechanism. A support member carries a displacement rod that is movably mounted on the support member. The motor is with its actuating end connected to the support member. The gear mechanism includes a hinge member allowing pivoting of the displacement rod about a pivot axis that is oriented transversely to the longitudinal axis. The gear mechanism engages with the displacement rod and the support member is hingingly attached to a fixation bracket in a hinge connection that is hingeable about an axis which is oriented transversely to the longitudinal axis. The drive member can be used for the adjustment of the backrest of a rear seat in a motor vehicle.

Proposed is a support driver for a seat and a support assembly including the same. The support driver is configured to operate within a limited space while supporting an occupant comfortably and safely. The support assembly has a structure in which the links push the central portion of the cushion in close contact therewith while remaining in intersection with each other. Advantageously, the links are able to push the cushion with a minimum amount of power within a limited space.

A vehicle seat including a pivot bracket, a back frame, a linear adjustment mechanism, a striker, and a latch. The back frame is pivotally connected to the pivot bracket and configured to pivot about a pivot axis. The back frame includes a first end spaced apart from the and disposed below the pivot axis. The latch is configured to selectively attach the linear adjustment mechanism to the first end of the back frame so that as the first linear adjustment mechanism translates, the back frame pivots from a first use position and a second use position, and selectively detach the linear adjustment mechanism from the first end of the back frame so that the back frame is pivotable to a non-use position.

A vehicle seat includes a seat bottom coupled to floor of a vehicle and a seat back coupled to the seat bottom to move relative to the seat bottom. The seat back includes a backrest and a backrest adjuster configured to move relative to the backrest to change a shape of the backrest.

A gear for an adjusting device in vehicles for adjusting two vehicle parts adjustable relative to each other, in particular, for adjusting two parts of a seat adjusting device, a window lifter, or a sun roof, the gear including a drivable drive screw having gear teeth, a spindle nut, which has spindle nut teeth engaging with the screw teeth, and an internal thread, using which the spindle nut can be brought into engagement with a threaded spindle of the adjusting device, and a gear housing, which accommodates and supports the drive screw and the spindle nut. The spindle nut is made at least partially of metal, and the drive screw is made of plastic, and the gear housing includes a first bearing section made of plastic for supporting the spindle nut and a second bearing section made of metal for supporting the drive screw.

A reclining seat assembly includes a seat frame, and a backrest frame supported by the seat frame for pivoting movement about a backrest pivot axis. A seat pan has a forward portion supported by the seat frame for relative longitudinal movement, for example, using a slider. The seat pan has a rearward portion that is pivotally supported along a rear seat pan axis by a lower extension of the backrest frame, such that the backrest frame reclines relative to the seat frame upon forward longitudinal movement of the rear seat pan pivot axis relative to the seat frame. A backrest recline angle adjuster on the seat frame, such as a pair of linear actuators respectively coupling the seat frame to each side of the backrest frame along an actuator pivot axis that is itself offset from the backrest pivot axis, maintains a selected position of the rear seat pan support axis relative to the seat frame to thereby achieve a desired backrest inclination.

A device for tilting a seat cushion of a fold and dive seat includes: a pair of seat cushion side frames spaced apart from each other; seat back side frames connected to the pair of seat cushion side frames; a seat cushion main-frame connected to the seat back side frames; guide brackets, one of which disposed on a first side of a front portion of the seat cushion main-frame and another of which disposed on a second side of the front portion of the seat cushion main-frame, wherein each of the guide brackets has a longitudinal through-hole; a tilting support bar, both ends of which extend through the through-holes, respectively; tilting support links, each of which connected between the tilting support bar and each seat cushion side frame; a mounting bracket disposed on the front portion; and a tilting drive device disposed between the mounting bracket and the tilting support bar.

A vehicle seat including a pivot bracket, a back frame, a linear adjustment mechanism, a striker, and a latch. The back frame is pivotally connected to the pivot bracket and configured to pivot about a pivot axis. The back frame includes a first end spaced apart from the and disposed below the pivot axis. The latch is configured to selectively attach the linear adjustment mechanism to the first end of the back frame so that as the first linear adjustment mechanism translates, the back frame pivots from a first use position and a second use position, and selectively detach the linear adjustment mechanism from the first end of the back frame so that the back frame is pivotable to a non-use position.

Clutch-based adjustment mechanism for motorized multi-way seat adjustment An adjustment mechanism comprises multiple screw shafts (111, 112, 113) and a motor (150) for driving the screw shafts. Further, the adjustment mechanism comprises a clutch mechanism (160) for selectively engaging the motor (150) with one or more of the screw shafts (111, 112, 113). A rotation of one or more of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a first degree of freedom. A rotation of one or more others of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a second degree of freedom.
