To provide a vehicle seat with a function of reducing fatigue regardless of the physique of the seated person, a vehicle seat includes: an ischial tuberosity support device that is driven to change a position of a part of a seat cushion corresponding to ischial tuberosities of a seated person; a sacrum/ilium support device that is driven to change a position of a part of a seat back corresponding to the sacrum and ilia of the seated person; a ninth thoracic vertebra support device that is driven to change a position of a part of the seat back corresponding to a ninth thoracic vertebra of the seated person; and a control device, wherein the control device sequentially executes: an information acquisition step of acquiring physique information of the seated person; a decision step of deciding parameters regarding a driving amount of each of the ischial tuberosity support device, the sacrum/ilium support device, and the ninth thoracic vertebra support device based on the acquired physique information; and an output step of driving the ischial tuberosity support device, the sacrum/ilium support device, and the ninth thoracic vertebra support device based on the corresponding parameters.

A headrest (1) of a vehicle seat includes a first head support device (1) and a second head support device (1). The headrest includes a tilting device (7) for tilting the first head support device (1) relative to the second head support device (1). The headrest (1) includes a height adjusting device (9) for adjusting the height of the first head support device (1) relative to the second head support device (1). A vehicle seat is also provided including an arm rest and a device.

An exemplary embodiment of the present disclosure relates to an armrest apparatus and an industrial vehicle including the same, and the armrest apparatus disposed in a driver seat includes: an armrest body which supports an operator's arm; and a drive unit which has a variable length, provides power to move the armrest body upward, and absorbs force applied in a direction in which the armrest body moves downward.

An armrest assembly for an aircraft passenger seat including a base, a first arm having a first end pivotally attached to the base, a second arm having a first end pivotally attached to the base, and an arm support element pivotally connected to a second end of the first arm and pivotally connected to a second end of the second arm. An assist device applies force to bias the arm support element from a first position toward a second position higher than the first position. The base, the arm support element, the first arm, and the second arm operate together as a four-bar linkage system. Upon actuation of a user-actuatable release device, the arm support element can be moved from the first position to the second position with force assistance from the assist device.

The invention relates to a vehicle seat with at least one laterally positioned operating device for operating the vehicle seat functions and/or vehicle functions and an adjustment device for adjusting a vertical position and/or an inclination of the at least one operating device with respect to a rest of the vehicle seat, wherein the adjustment device comprises a rotational axis extending in the seat width direction and a shaft which is connected to the operating device, positioned at a distance from the rotational axis and rotatable together with the operating device about the rotational axis, wherein the adjustment of the vertical position and/or of the inclination of the operating device is feasible by means of a rotational movement of a spindle element which is in operative contact with the shaft, wherein a central axis of the spindle element is perpendicular to a central axis of the shaft.

An adjustable motor vehicle seat includes a main part, an attachment which is movable relative to the main part, and a guide element which includes a receiving portion configured for receiving the main part or the attachment at least in part and having a surface which has at least one portion shaped spherically. The guide element is mounted in a bearing point of at least one of the main part and of the attachment, said bearing point having a cross section which at least in one portion is circular.

A vehicle with a flat seat may include a floor portion having a leg groove recessed downward from a surface of the floor portion; a seatback disposed on the floor portion and reclining by a rotation of the lower end; a seat cushion disposed on the floor portion ahead of the seatback; and a leg cushion disposed in the leg groove of the floor portion and having a rear portion rotatably coupled to the seat cushion.

An armrest assembly for a vehicle seat, the assembly comprising an armrest, a support, and an intermediate portion, the armrest being movable in translation along a vertical direction relative to the support, the assembly further comprising a locking device for the armrest comprising: a first part having toothed elements, and a second part capable of coming into contact with the toothed elements of the first part, and wherein the second part is movable between a locking position in which the second part is in contact with the toothed elements of the first part and an unlocking position allowing movement in translation along the vertical direction of the armrest.

An armrest assembly for a passenger seat includes a pivot member (101) attached to a seat frame (10), at least one armrest spine (102) attached to the pivot member (101), and at least one set screw (106) for adjusting a position of the pivot member relative to the seat frame. A pivot fastener (112) extends through a center hole of the pivot member (101) and through a first hole of the at least one armrest spine (102). A pin (110) extends through an arc slot of the pivot member (101) and through a second hole of the at least one armrest spine (102).

An adjustable motor vehicle seat includes a main part, an attachment which is movable relative to the main part, and at least two guide elements. Each guide element has a surface which is spherical in at least one portion, and a receiving portion configured for receiving the main part or the attachment at least in part. The guide elements are mounted in a bearing point of at least one of the main part and the attachment and arranged one behind the other with respect to a direction of translation of the attachment relative to the main part.
