摘要:
A seat assembly (21) for a vehicle including a seat (22), a seat mounting assembly (20) mounting the seat for movement along an upwardly concaved arcuate path, a backrest assembly (25) having a lower backrest portion (18) coupled for motion with the seat and an upper backrest portion (99) mounted in a vertically extending direction. The backrest assembly further includes a recliner frame and mechanism (32, 33). The seat assembly, also including the steps of mounting the seat (22) for spherically guided movement along said path, mounting the backrest proximate the seat. The assembly (21) and method disclosed further employs mounting the seat (22) having a spherical surface (161) and guide track (28) the guide track mated to spherical support surface (162), and may include slider roller elements (27, 142) such that the seat mounting assembly accommodates lateral, diagonal and fore and aft seat motion (35, 163).

A vehicle seating assembly includes a seatback and a seat base pivotally coupled with the seatback. An upper link is pivotally coupled between an upper portion of the seatback and a rear support. A front link and a rear link are pivotally coupled between the seat base and a floor. A bottom end of the front link is moveable on the floor between a forward position and a rearward position, adjusting the seatback respectively between a reclined position and an upright position.

A seat height and tilt adjustment apparatus includes first and second arms mounted between two structures. The first arm is pivotally attached to the first structure at the first pivot axis, and pivotally attached to the second structure. The second arm is pivotally attached to the first structure at a second pivot axis and pivotally attached to second structure. A linkage is pivotally attached to the first structure at a third pivot axis and pivotally attached to the first arm. A first actuator adjusts the distance between the two structures by simultaneously varying the distance between the first and second pivot axes and the distance between the first and third pivot axes. A second actuator varies the tilt of one structure relative to the other structure by varying the distance between the first and third pivot axes, while maintaining a constant distance between the first and second pivot axes.

A vehicle seating system for adjusting, without rails, the vertical and longitudinal position and the inclination of a vehicle seat relative to a vehicle floor has, in one embodiment, first and second pivot levers, spaced apart from one another in an adjustment direction. The pivot levers are articulated respectively on the vehicle seat and on the vehicle floor by way of pivot pins extending parallel to one another. The pivot pins arranged on the vehicle seat and on the vehicle floor of at least one of the pivot levers are lockable independently of one another.

The invention concerns a seat (1) with at least one seat base part (2) and at least one backrest part (3) which seat is supported on a seat carrier (4) and is movable in relation to said carrier by positioning drive (5, 6). Considering one of possibly multiple seats (1) it is of advantage, that the positioning drive (5, 6), is in controlling connection with at least one body position sensor (12, 13) to enable the advancing or retracting of a seat base part (2) and/or a backrest part (3) in accord with the bodily position assumed by a person on said seat (1), or, for the retraction of the seat base part (2) and or backrest part (3) in accord with a bodily movement of a person on the seat (1). In this arrangement, the seat base part (2) and/or the backrest part (3), are movably guided in an enforced guidance and pivotally connected to one another by a pivot connection (7), and in addition the seat base part (2) and the backrest part (3) are guided, at a prescribed distance from the pivot connection (7), and can rotate about their guide axes or guide pins (8, 9). This seat (1) is especially comfortable and simple to manipulate and offers an ergonomically favorable arrangement in any adjustment position for the user, because of the enforced guidance system, and the linkage (7) in connection with seat base part and backrest part.

The invention relates to a seat frame of a motor vehicle seat with a seat carrier having two side parts that are oriented transverse to a front axis and to a rear axis, a pivotal bridge being pivotal about at least one of said axes, said bridge comprising a tie bar and two side arms, and with an adjustment device having a motor-driven drive unit. The drive unit is arranged for pivotal movement about a hinge shaft that is substantially centered on that axis of the two axes about which said pivotal bridge is pivotal. Said hinge shaft is shorter than the distance between the two seat parts and is not in contact with said two seat parts, but if at all with only one side part. There is provided at least one inner arm that connects said tie bar to said hinge shaft and is located in proximity to said drive unit.

A vehicle seat assembly comprises a coupling member 12 coupling a front end of a seat-cushion frame 2 to an upper rail 11, a rear link member 23 provided in a rear end of the seat-cushion frame 2, and a support member 24 provided on the side of a vehicle body to support the rear link member 23. The rear link member 23 includes a pivoted portion 26 pivotally supported by the upper rail 11, a coupled portion 28 coupled to the rear end of the seat-cushion frame 2, and an engaged portion engaged with the support member 24. The support member 24 includes a sliding drive portion (sliding groove 33) which slidably supports the engaged portion of the rear link member 23 to allow the rear link member 23 to be swingingly displaced in conjunction with a longitudinal movement of the seat-cushion frame 2, so as to move the coupled portion 28 in an upward/downward direction to drivingly lift and lower the rear end of the seat-cushion frame 2. The vehicle seat assembly of the present invention can effectively a height position of a seat cushion in conjunction with an operation of adjusting a longitudinal position of an occupant seat in conformity to occupant's physique or the like.
