A vehicle seat having a pivoting function about a vertical axis, the seat comprising a pivoting assembly) with a base, a rotating ring mounted on the base by means of a hinge mechanism interposed between the base and the rotating ring, a seating portion frame connected to the rotating ring, directly or via a raising mechanism and/or longitudinal rails, the hinge mechanism allowing rotation, about a vertical main axis, of the rotating ring relative to the base and blocking any substantial movement in the other degrees of freedom, namely the other two rotations and the three translations in an orthogonal reference system.

A lateral shock absorber includes a protective fender and a locking mechanism. The protective fender is pivoted to a base of a child car safety seat and pivotally switchable between a folded state or an unfolded state relative to the child car safety seat. The locking mechanism is for selectively engaging with the protective fender to restrain the protective fender from switching to the unfolded state or disengaging from the protective fender to allow the protective fender to switch to the unfolded state when the protective fender is located in the folded state. The protective fender includes a driving block, a supporting block and a combining assembly. The driving block is pivoted to the base, and the supporting block is pivoted to the driving block and engages with the driving block by the combining assembly.

A vehicle occupant restraint device includes: a seat cushion on which an occupant is seated; a seat back that is provided on a seat rear side of the seat cushion so as to be pivotable in a seat front-rear direction and that supports a back of the occupant; an ottoman provided on a seat front side of the seat cushion so as to be pivotable in a seat up-down direction; and a fabric restraint member that is extended in a width direction of the ottoman to restrain a lower limb including a knee of the occupant when at least the ottoman is set in a raised position and the seat back takes a comfortable posture.

A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

A side-impact crash structure for a vehicle seat may be positioned in the side wall of a passenger seat to reduce impact forces imparted to an occupant during a side collision. The side-impact crash structure for the vehicle seat may include energy absorbers positioned between the seating surface and the outer sidewall of the vehicle. The energy absorbers may be positioned to engage the shoulder and/or lower abdomen area of the passenger. The energy absorbers may be configured to absorb impact forces over a limited ride-down distance (the distance over which the deceleration occurs) to prevent injury to occupants.

A system reduces motion sickness symptoms in operation of a vehicle. The system has a control unit which is coupled to a sensor system and/or to a navigation system, to a vehicle seat system, to a vehicle stabilization device and to a display unit for receiving and/or emitting signals. The sensor system and the navigation system are set up to receive environmental data and/or vehicle component data relating to the vehicle, from which movements of the vehicle result, and to transfer the data to the control unit. The control unit is set up to generate vehicle stabilization signals, seat adjustment signals and display signals on the basis of the received environmental data and/or vehicle component data.

Provided is a vehicle seat having a seat back that can be folded forward, in which the buckle is prevented from interfering with the seat hack when the seat back is folded forward. A seat cushion frame (F1) rotatably attached to the seat back frame (F2) includes a pair of side frames (11) extending in a fore and aft direction, a front frame (12) extending between front parts of the side frames, and a rear frame (13) extending between rear parts of the side frames and provided with a curved portion (13A) protruding forward in a middle part thereof. A buckle support arm is located behind the curved portion, the curved portion being dimensioned so as not to interfere with the buckle when the buckle support arm is in a stowed position.
