A seat with a headrest for a locomotive means includes a carrier or support system for a backrest of the seat, a support element having an installation section, and a guide device. The headrest has a headrest box, wherein the installation section of the support element is arranged on the support system in a stationary manner in the region of the headrest. The headrest box is movably arranged on the guide device, and the headrest box can be locked relative to the guide device in a movement direction.

A vehicle seat (1) is provided with a cushion frame (5) that can be moved up and down by means of a link mechanism (6). To assist the upward movement of the cushion frame (5), a torsion bar (14) is disposed in a connection pipe (12) having both ends secured to a pair of left and right rear links (11, 11). A position holding member (24) holds the torsion bar (14) and is supported by the connection pipe (12), whereby the positional shift of the axis of the torsion bar (14) is suppressed. The position holding member (24) engages an extension portion (16) extending perpendicular to the shaft portion (15), and thus, does not rotate around the axis relative to the torsion bar (14). Therefore, in the position holding member (24), portions requiring reinforcement against a transverse force from the torsion bar (14) are limited a narrow range, and the position holding member (24) can be reduced in size and weight.

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 comprising: a seat base frame, anchoring means for anchoring to the floor of a vehicle, a backrest pivotably hinged to the seat base frame, a substructure pivotably hinged to the anchoring means and to the backrest, a front connecting rod pivotably hinged to the anchoring means and to the seat base frame, a sector gear pivotably hinged to the anchoring means, an irreversible electric motor configured to cause rotation of the sector gear relative to the anchoring means, a first locking means for locking the rotation of the substructure relative to the anchoring means, a second locking means for locking the rotation of the backrest relative to the substructure, a third locking means for locking the rotation of the front connecting rod relative to the sector gear.

A seat of a vehicle comprising a seat base, fixation means for fixing to the floor of a vehicle, a front connecting rod pivoting along a first axis at the fixation means and along a second axis at the base, a lower rear connecting rod pivoting along a third axis at the fixation means, an upper rear connecting rod pivoting along a fourth axis at the base and along a fifth axis at the lower rear connecting rod, a locking means able to transition: from a locked state, wherein it prevents the rotation of the lower rear connecting rod in relation to the upper rear connecting rod, to an unlocked state, wherein it enables the rotation of the lower rear connecting rod in relation to the upper rear connecting rod, and conversely.

A seat device that can reliably prevent a rotation operation of a seat by a seated person, in a long state where the back of the seat is along a wall. A rotation lock mechanism (60) that can restrain the rotation of a seat (1), a rotation operation unit (200) that performs a release operation of restraint by the rotation lock mechanism (60), and a rotation operation prevention mechanism (210) that disables the release operation in the rotation operation unit (200), when the seat (1) is in the long state are included. The rotation operation prevention mechanism (210) includes an engaging unit (211) provided in the leg stand (11), and an engaged unit (207) that is provided in the rotation operation unit (200) in the movable stand (20), and disables the release operation in the rotation operation unit (200) by being engaged with the engaging unit (211) when the seat (1) is in the long state.

A convertible seat for a vehicle includes a base frame having a predetermined dimension of storage space, a plurality of individual blocks disposed to be ascendable and descendable in the storage space of the base frame and configured to serve as a seatback and a seat cushion, and a raising and lowering drive device installed in each of the individual blocks and configured to raise or lower a corresponding one of the individual blocks so that a seat position can be changed into various forms.

The disclosure discloses an automobile seat based on an inclined angle adjustment mechanism, including a seat body composed of a cushion skeleton, a backrest skeleton, and a base arranged under the seat body. The upper surface of the base is of a non-plane structure and includes a pedestal located at the lower part and a branch located at the upper part which is integrated or connected by a fixed member, the back of the pedestal is movably connected with the lower part of a third connection rod, the upper part of a seventh connection rod is movably connected with the front of a forth connection rod, and the middle of the seventh connection rod is movably connected with the upper end of the branch, and rotation points are located near the H point of the seat.

The present disclosure relates to an anti-pinch control system. The anti-pinch control system includes a motor configured to generate driving force for moving a seat of a vehicle, a pressure sensor configured to detect a pressure applied to the seat, a current measurement sensor configured to measure an amount of current generated by the motor, a database unit configured to store data on an amount of current required to drive the seat that corresponds to the pressure detected by the pressure sensor, and a controller configured to vary an anti-pinch value of the seat based on data corresponding to the pressure applied to the seat.

A seat adjustment system for a vehicle seat is provided. The seat adjustment system includes a seat body; at least one actuating unit, configured to adjust a support of the seat body; a sensing unit, configured to obtain and provide seat information and body shape data of a back of an occupant; and a control unit, configured to control the at least one actuating unit; wherein when one parameter of the seat body changes, the control unit makes a portion of the body shape data of the occupant in a pre-defined range via the at least one actuating unit.
