Embodiments described herein relate 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 deformation element for a motor vehicle seat, which element is intended to be arranged on a subassembly of a motor vehicle seat, having a base member, a deformation portion which is formed on the base member and on which the deformation element can be deformed and/or destroyed under the action of an external force, and a force introduction region by means of which a structural element of a motor vehicle seat can be brought into operational connection with the deformation portion so that a force acting on that structural element can be introduced via the force introduction region into the deformation portion. The deformation portion is formed by means of partial deformation of the material of the deformation element and at the transition of the deformation portion to the base member of the deformation element there is a weakening region which defines at least one tear line.

The invention relates to a height-adjustable control lever carrier for a commercial vehicle seat, which carrier is at least partially arranged to the side of a seat part, wherein the control lever carrier is provided for receiving at least one control lever for controlling vehicle equipment and at least one armrest, and is characterised in that the control lever carrier comprises a multi-joint mechanism construction, by means of which the control lever carrier is adjustable both in a seat height direction and in a seat longitudinal direction relative to the seat part.

The present invention relates to a seat five-link structure (A), comprising a bottom support (1), a wall plate (3), a first front link (4), a second front link (5) and a rear link (2), wherein the bottom support (1) is pivotally connected with the first front link (4) through a first pivot axis (O.sub.1), the first front link (4) is pivotally connected with the second front link (5), the second front link (5) is pivotally connected with the wall plate (3), and the rear link (2) is pivotally connected with the bottom support (1) through a second pivot axis (O.sub.2) and is pivotally connected with the wall plate (3); a first electric motor (8) configured to output a first external force for driving the first front link (4) to rotate around the first pivot axis (O.sub.1); and a second electric motor (12) configured to output a second external force for driving the rear link (12) to rotate around the second pivot axis (O.sub.2). The seat five-link structure (A) according to the present invention may have a larger adjustment range of an inclination angle and a seat height, which is beneficial to the realization of a zero-gravity function and allows an occupant better vision and better comfort.

A vehicle seat device lifts and lowers a seat. The vehicle seat device includes a base, a lifter link, and a drive device. The lifter link includes a plurality of members that move a seat cushion of the seat vertically relative to the base. The drive device is coupled to the lifter link. The drive device relatively moves the lifter link. The drive device is attached to the base, a vehicle floor, or a seat-mounting device fixed to the vehicle floor.

Various seating arrangements for a vehicle are described. Generally, the vehicle includes an electromagnetic array featured on a floor of the vehicle. The chair includes base having a plurality of magnets featured thereon. The vehicle generates signals for the electromagnetic array to generate a wave and impart a force on the chair in a determined direction via the plurality of magnets.

A height-adjustable seat includes a seat part having a frame and a back part. At pivot lever is pivotally mounted about a pivot axis for height adjustment of the seat by a pivoting movement of the pivot lever. A movable connecting member is connected to the pivot lever by a first pivot lever joint so that a movement of the connecting member causes a pivoting movement of the pivot lever about the pivot axis. An actuating member moves the connecting member with a gear wheel. A movable transmission member having teeth transmits a force from the gear wheel to the connecting member. The gear wheel meshes with the teeth of the transmission members, which is in mechanical operative connection to the connecting member so that a movement of the transmission member causes movement of the connecting member. The connecting member is mounted to a base part and subjected to a compression load.

An actuating device (100) has a first part (5a; 334; 434) and a second part (5b; 310; 412) which can be pivoted about a first axis (A) relative to the first part (5a). A first segment (140) can be coupled to the first part. A second segment (150) can be rotated about the first axis (A) relative to the first segment (140) and can be connected to a locking device of a component (20) and/or to a locking device (350; 450) of another component (330; 430). Rotation of a deflecting element (120) moves a transfer element (130) such that the second segment (150) is not rotated about the first axis (A). Changing a distance between the first axis (A) and a second axis allows the second segment (150) to be rotated about the first axis by the transfer element (130). A vehicle seat includes such an actuating device (100).

A method is provided for connecting a first component to a second component, wherein the first component has a deformation region. The deformation region is at least partially heated in a first step. In a second step an inner die, having an optical component for plastic deformation, is provided. In a third step the first component is plastically deformed in the deformation region in order to connect the first component to the second component. Light for heating the first component is directed at the deformation region by means of the optical component of the inner die in the first and/or third step.

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.
