A vehicle seat including a seat cushion including a cushion body that supports buttocks of an occupant, and cushion side portions disposed on both seat width direction sides of the cushion body, a seatback including a back body that supports a back of the occupant, and back side portions disposed on both seat width direction sides of the back body, and an adjustment mechanism including at least one of a cushion adjustment mechanism that on actuation moves the cushion body in a seat up-down direction with respect to the cushion side portions and pivots the cushion body about an axis running along the seat width direction, or a back adjustment mechanism that on actuation moves the back body in a seat front-rear direction with respect to the back side portions and pivots the back body about an axis running along the seat width direction.

The present invention relates to an end part for a cross member for a vehicle seat, a cross member for a vehicle seat comprising at least one end part, and a vehicle seat comprising at least one such cross member. The end part has a first portion with an impact receiving surface adapted to receive an impact during a side collision. The cross member has a longitudinal center line. A center point of the impact receiving surface is offset with respect to the longitudinal center line so as to bend the cross member in a predetermined direction during the side collision. The present invention provides for a simple way to modify a cross member, or to provide a cross member with additional functionality and increased safety properties.

A vehicle seating assembly includes a lower leg support, a seat, and a seatback. A seat rotational member rotatably couples the lower leg support to the seat. A seatback rotational member rotatably couples the seat to the seatback.

Provided is a boarding/deboarding controller that enables reduce time and effort for boarding and deboarding a vehicle of which canopy is opened or closed to allow a user boards or deboards. One aspect of the present disclosure provides a boarding/deboarding controller for a vehicle including a seat, an occupant compartment provided with the seat, and a canopy that moves to a closed position where the canopy covers the occupant compartment and to an opened position, which is situated upper than the closed position. The boarding/deboarding controller is configured to change a posture or position of the seat concurrently while the canopy is moved from the closed position to the opened position in an opened movement, or, from the opened position to the closed position in a closed movement.

[Purpose] To provide a link structure in a motor vehicle seat, which realizes a simplified pivotal connection of a link element therein and also ensures that rotation of the link element is maintained so smooth and stable as to avoid rattling and wobbling of the link element.

[Means for Achieving the Purpose] In a link structure comprising a movable portion (such as a seat cushion frame D) and a base portion (such as an upper rail member D) retained stationary relative to the movable portion, wherein the movable portion is movable relative to the base portion and connected therewith via a link element 10, there is provided a pivotal connection portion E to which the link element 10 is at a hole portion 10a thereof pivotally connected. This pivotal connection portion E basically includes: a cylindrical region 11a-1 integral with one or each of the base and movable portions; and an outwardly-divergent opening end region 11a-2 formed in a free end of the cylindrical region so as to become large radially in an outward direction. The hole portion 10a of the link element 10 is rotatably supported on and about the cylindrical region 11a-1, while a lower end portion 10eL of the link element is supportively sandwiched between the outwardly-divergent opening end region 11a-2 and one or each of the base and movable portions, so that the link element 10 is ratable relative to the cylindrical region 11a-1 forming a center of rotation of the link element. With this arrangement, the pivotal connection of the link element can be effected in an extremely simplified manner, and further, in assembly, merely pressing and deforming the cylindrical region 11a-1 preformed in the base portion results in a completely uniform formation of the outwardly-divergent opening end region 11a-2, such that a circular foot base 11c of that outwardly-divergent opening end region is fully contacted with an entirety of an edge 10aE of the aforesaid hole portion 10a, thus establishing a full and uniform circumferential contact therebetween. Accordingly, the pivotal connection of the link element 10 to the base portion side can be extremely stable, so that the link element 10 is smoothly rotatable about the cylindrical region 11a-1, without any rattling and wobbling of the link element there.

Provided is a vehicle seat including a height device for moving up and down a seat body and being capable of suppressing a positional displacement of the height device. A vehicle seat includes a cushion frame serving as a framework of a seating portion, a height device for moving the cushion frame up and down, and a side cover that covers the cushion frame and the height device from the outsides thereof in the seat width direction. An operation lever and a brake unit, which serve as components of the height device, are disposed separated from each other. The operation lever is positioned to be engaged with a positioning member housed in an outer surface of the side cover.

An assembly group of a vehicle seat comprises a tube element having a tube section extending along a longitudinal direction and a bead section formed on the tube element and radially protruding with respect to the tube section. An attachment part is connected in a torsionally locked manner to the tube element and has a planar section and a first opening formed in the planar section, wherein the tube element extends through the first opening such that the tube element with the bead section abuts the planar section of the attachment part. The attachment part comprises at least a second opening separate from the first opening. The bead section comprises at least one protrusion element engaging with the at least one second opening for torsionally locking the tube element with respect to the attachment part.

Vehicle seat (1), with a seat part (2) and a backrest (3), which comprises a lumbar support (7), wherein the lumbar support (7) has a lumbar apex (7.1) towards the back of a seat occupant and tapers from there and that the lumbar support comprises a suspension 9, 11, 12) that results in load distribution with a primery load uptake (8. 1) at the lumbar apex (7.1).

Longitudinal, adjuster (27) having an outer and an Inner rail (50, 51), characterized in that the outer rail (50) has a structural element (53) which absorbs vertical forces and has a flexible element which biases a rolling body (52) against the inner rail (51).
