A fold and dive seat for a vehicle that achieves a fatigue reduction posture is provided. The seat includes a tip up-extension mechanism that enables tipping-up and extension of the front end of a seat cushion and a seatback reclining mechanism for the fold and dive seat so that tipping-up for lifting the front end of the seat cushion and extension for extending the front end forward are performed simultaneously performed when the seatback reclining is performed.

A position control system is disclosed that replaces a parallelogram or quadrilateral movement system with greater efficiency, economy, stability and utility by eliminating one of the four links and providing a non-linear path to be followed. This system includes a dynamic triangular mechanism for movement from a first position to at least a second position, with at least three (3) link members interconnected by pivots with a first base link member defining a non-linear path, said first base link member having a fixed base pivot and a follower pivot that moves along the non-linear path, a second fixed length support link member pivotally connected to the fixed base pivot, and a third follower link member pivotally connected to, and located between, the follower pivot and a connector pivot, wherein the follower link member is adapted for following the non-linear path, thereby creating a virtual triangle defined by the three link members while the follower pivot, fixed base pivot and the connector pivot interconnect the first base link member, the second fixed length support link member and the third follower link member.

A vehicle seat having a base (10) and a squab (11) and an adjustment mechanism (20) whereby the position of an occupant sitting in the seat can be adjusted, the mechanism being configured so as to permit the seat to follow a motion path that provides coordinated adjustment of both height and back inclination of the occupant, the motion path being such that as the height of the occupant is raised the back inclination of the occupant becomes less supine.

Arrangements for safety and comfort in vehicles.

Proposed is a clutch cam for a pumping device, wherein the shape of the clutch cam and the coupling structure between the clutch cam and parts coupled thereto are changed to reduce manufacturing cost and improve assembly performance. The clutch cam includes: a cam part having a cam profile provided along an outer circumferential surface thereof relative to a rotating axis of a center thereof; a first protrusion part provided on a side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to a fixing hole provided in the lever bracket; and a second protrusion part provided on the side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to an angle determination hole provided in the housing.

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.

A device for adjusting a seat of a vehicle is capable of implementing functions including adjusting a position of the seat back and forth, a height of the seat up and down, and tilting or the like by using a plurality of actuators having pistons. The functions of adjusting the position of the seat back and forth, the height of the seat up and down, and tilting or the like are carried out by providing connections between a floor panel and a seat cushion frame through a plurality of actuators and a single link, and selectively moving a piston of each actuator back and forth.

A vehicle seat that includes: a cushion frame rear portion that is rotatable around a rear portion shaft, whose axial direction is a seat transverse direction, with respect to a vehicle body floor portion; a cushion frame front portion that is connected to the cushion frame rear portion so as to be rotatable around a center fold shaft whose axial direction is the seat transverse direction and that is positioned further toward a seat front side than the rear portion shaft; a seatback frame that stands erect from a rear end side of the cushion frame rear portion; and a driving mechanism that moves the cushion frame front portion and the cushion frame rear portion relatively in a seat vertical direction between a non-reclining state and a reclining state, in which the cushion frame rear portion tilts downward and rearward with respect to the cushion frame front portion.

A passenger seat for an aircraft has a fixed seat portion with a front facing toward a first direction of the aircraft. The fixed seat portion has a centerline spaced equally from opposed lateral sides of the fixed seat portion. A first engagement member extends upwardly from the front at the centerline to a first engagement end. A moveable seat portion is mounted onto the fixed seat portion and is displaceable relative thereto. The moveable seat portion has a second engagement member extending downwardly from a front of the moveable seat portion to a second engagement end. The second engagement member is displaceable with the moveable seat portion to position the second engagement end under the first engagement end in an engagement position such that the overlapping first and second engagement ends prevent the moveable seat portion from pitching in a second direction opposite to the first direction.
