A lock assembly for a vehicle seat includes a lever that has a body and a retention tab that extends from the body, a biasing member that is operably coupled to the body of the lever, an engagement member that is proximate to the lever, and an inertia member that has a weighted head and a retention hook. The inertia member is operable between a first position and a second position.

A vehicle seat comprising a seat part extending in the vehicle longitudinal direction (X) and in the vehicle transverse direction (Y) and including a backrest part is provided. The vehicle seat includes a seat substructure for suspending and/or damping at least the seat part with respect to the body of a vehicle. The seat substructure comprises at least one horizontal suspension device that includes a body-side lower part and a seat-part-side upper part displaceable with respect thereto. A coupling device is arranged interactively between the seat-part-side upper part and the body-side lower part, and includes a deformable suspension element as a first coupling element and a bearing and deformation device as a further coupling element.

A seatback frame including left and right side frames, a lower frame, and a sacrum support section. The left and right side frames extend in a seat up-down direction inside left and right side portions of a seatback of a vehicle seat. The lower frame spans between lower end portions of the left and right side frames. The sacrum support section extends from a lower end portion of the lower frame toward a seat front side and supports a sacral region of a seated occupant from a seat rear side. A weakened portion that is weakened by a load from the seat front side is provided to the sacrum support section.

A vehicle seat frame includes a seat cushion frame, left and right links, a connection member, left and right slide rails, and left and right risers. The seat cushion frame includes left and right side frames. The left and right links each have a one end portion connected to respective front portions of the left and right side frames. The connection member connects the left and right links together in the seat left-right direction. The left and right slide rails are disposed below the left and right side frames and are attached to a floor section of the vehicle. The left and right risers are respectively attached to the left and right slide rails, are connected to respective other end portions of the left and right links, and are configured to be impacted by the connection member under load from the occupant during a head-on collision of the vehicle.

A vehicle seat console includes at least one vehicle-side guide element and at least one seat-side guide element arranged parallel to the vehicle-side guide element. A length-adjustment device, which is acted on by a drive device and which is designed to bring about a relative displacement between the vehicle-side guide element and the seat-side guide element, is designed such that the length-adjustment device is provided between the seat-side guide element and a force-limiting apparatus, which is in turn coupled to the vehicle-side guide element.

In a vehicle seat frame, a connection member that connects left and right links together in a seat left-right direction is disposed below a rear portion of a cushion pan included in a seat cushion frame. A sloped surface sloped with a downward gradient toward a seat rear side is formed at a lower surface of the rear portion of the cushion pan. The sloped surface of the cushion pan slides in a seat rearward and diagonally downward direction relative to the connection member when the cushion pan deforms in a seat downward direction under load from the occupant during a head-on collision of the vehicle.

The present disclosure relates to an adjustment device for a head rest of a vehicle seat, including a locking device for adjusting a in relation to a back rest connection in a longitudinal direction and a vertical adjusting, where a locking device for locking the adjustment device is provided which comprises a release lever to be activated by the user which swivels a blocking element which in turn swivels a locking element.

A vehicle seat may include a protrusion member installed to a lower portion of a back frame inside a seatback to protrude forward and to absorb an impact on the hips of an occupant upon a vehicle collision, wherein a lower portion of the seatback, which has a protrusion shape due to the protrusion member, induces a sitting posture of the occupant to be modified when the occupant sits down on the vehicle seat, thereby reducing a gap between a head of the occupant and a headrest in a state that the hips of the occupant moves forward.

A seatback includes a lower frame, an upper frame, and a hinge coupling the lower and upper frames. An actuator is fixed relative to the lower frame, and a cable extends from the actuator to the upper frame. In the event of a collision, the actuator pulls the cable, and the upper frame moves from an upright position to a bent position relative to the lower frame.

A seat suitable for sports type automobiles with a low hip point. An energy absorbing structure part provided in a cushion frame is constituted of a substantially square frame body including a front beam and a rear beam, and stringers bridged across them and provided separately from side frames. It is structured such that belt anchor attaching members are each provided between a coupling position to a vicinity of a rear portion of upper rails of sliders and a coupling position of the rear beam in the stringers. When an impact force of a predetermined value or higher is applied, the stringers deform to absorb the impact force and trusses are formed after the deformation, thereby enabling to sustain a further impact force which continues to be applied.
