A seat adjustment mechanism for an adjustable seat assembly includes an arcuate tilt column; a lift column; a first tilt slider block detachably engaged to the lift column and slideably engaged to the tilt column for moving the lift column between a plurality of tilt positions; and a first lift slider block slideably engaged to the lift column for moving between a plurality of lift positions independent of the plurality of tilt positions. The slider blocks, the lift columns, the tilt columns and the cross brace may be made of dissimilar materials and/or are easily replaced with alternative components.

A vehicle seat includes a supporting member that supports a load of a seated person, a cushion frame, a rear pipe that is rotatably attached to the cushion frame, a lifter link that is fixed to the rear pipe, and a bracket that is rotatably attached to the rear pipe. An inclination of the cushion frame changes when the cushion frame is moved up and down by tilting the lifter link. The supporting member is connected to the rear pipe via the bracket.

An actuating drive for a rail guide of a longitudinal adjustment of a motor vehicle seat has a rotational drive, which has an output shaft (70), and a transmission, which has a spindle nut (54), which is rotationally connected to the output shaft (70) and which has a spindle (52). The spindle (52) has a spindle thread, with which the spindle nut (54) is engaged. The spindle (52) is curved in a circular radius of curvature (42). The radius of curvature (42) is between 1,500 and 3,000 mm. The spindle nut (54) is a straight nut.

A vehicle seat including: a connection mechanism; a seat cushion connected to an interior structure of a vehicle via the connection mechanism and configured to be displaced between a first state and a second state at which the seat cushion is arranged at a position closer to a front part-side of the vehicle than at the first state; and a seat back, wherein a sitting surface of the seat cushion at the first state gradually inclines upwardly from the rear of the seat towards the front of the seat, and wherein the connection mechanism is configured to displace the seat cushion to the second state and move a front part-side of the seat cushion more downwardly than at the first state, whereby the sitting surface of the seat cushion is made more horizontal at the second state than at the first state.

A vehicle seat has a base, a front pivotable link indirectly pivotably attached to the base, a rear pivotable link pivotably attached to the base, a seat frame, a seat cushion supported on the seat frame, and a backrest that is mounted on the seat frame by way of a fitting defining a backrest pivot axis. The seat frame is pivotably attached to the front pivotable link. The seat frame is pivotably attached to the rear pivotable link in a manner that defines a pivot axis (41) about which there can be relative pivoting between the rear pivotable link and the seat frame. The height and/or inclination of the seat cushion is adjustable relative to the base by moving the pivotable links. The pivot axis (41) is positioned rearwardly of the backrest pivot axis in at least one position of adjustment of the seat cushion and/or of the backrest.
摘要:
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 seat (11) having a seat cushion (12) and a squab (16), the seat (11) being adjustable between a first configuration adapted to provide seating accommodation for a user and a second configuration adapted to provide leaning accommodation for a user, wherein in the second configuration, the squab (16) is positioned forwardly of its position in the first configuration and substantially above the forward most position of the seat cushion (12).

A seat includes at least one inclinably adjustable seat component, such as a seat section (12), whose seat frame structure can be disposed on a floor structure (24) in such a way that the seating section is pivotable around its stationary legs (22). The pairs of stationary legs (22) in the region of the front edge (26) and the rear edge (28) of the seating section (12) act upon the seating section. An actuating device (30) adjusts the respective inclination of the seat section (12), and has an exit position, whereby the seat section (12) is orientated in an essentially parallel manner in relation to the floor structure (24) and cannot be inclined. The actuating device (30) extends in the exit position between the stationary legs (22), whereby one end (32) in the region of the front seat (26) is orientated counter to the floor structure (24) and the other end (34) in the region of the rear edge of the seat (28) is orientated in the direction of the seat frame structure (20). As a result, forces arising from a crash are deflected by the actuating device in a safe and targeted manner to the floor structure. The actuating device strives to maintain its original position in the seat frame structure when a crash occurs.
摘要:
An actuator mechanism includes a attachment member fixed to a seat elevation adjuster and a controlling member placed between a driver member and the attachment member and can rotate together with an actuating lever. The driver member is located between the attachment member and a rotary member and fitted over a center shaft. There is formed a feed projection at one terminal portion of the driver member and its opposite terminal portion is placed face to face with a locking member. When the actuating lever is operated, the controlling member moves the driver member, which causes the locking member and the feed projection to engage with and disengage from the rotary member.
