A clip for providing a sliding force towards a movable substrate, the clip including at least one strip, where the at least one strip comprises a first axial end and a second axial end and an arcuate shape between the first axial end and the second axial end; where the at least one strip is a metal strip including a sliding layer at an outbound side.

A headrest level adjustment mechanism includes a main support that is provided on a side of a main headrest stay, and cooperates with the main headrest stay to provide a locking mechanism that adjusts a level of the headrest and locks the headrest at a predetermined level, and a sub support that is provided on a side of a sub headrest stay, and cooperates with the sub headrest stay to provide a movement restriction mechanism that restricts downward movement of the headrest and keeps the headrest at a lowest-level position, in a condition where the main headrest stay is engaged with the main support, and a gap is provided between the headrest and a seat back, the main headrest stay and the sub headrest stay being held by the seat back and hanging down from two positions of the headrest spaced from each other in a seat width direction.

A headrest assembly may have a connecting member extending between a headrest and a seat back of the headrest assembly. A mechanism may be located in the headrest assembly or the seat back. The mechanism permits selective movement of the headrest with respect to the connecting member.

To reduce the weight of a cross member bridged between right and left sides of a seat frame. A seat frame includes an upper frame forming an upper portion of a seat back frame, and a cross member bridged at the upper frame. The cross member includes right and left end portions in a seat width direction, the right and left end portions being fixed to the upper frame; and a first recessed portion that is recessed upward or downward and provided between the right and left end portions. The first recessed portion is provided at a center portion of the cross member in the seat width direction.

An automotive seat with headrest assembly includes a seatback, a headrest, and a pair of headrest supports adapted to support the headrest on the seatback, each of the headrest supports including a lower rod, an upper rod, and an absorption unit positioned between and interconnecting the lower rod and the upper rod, the absorption unit adapted to allow angular deflection of the upper rod relative to the lower rod when a bending force is applied to the upper and lower rods, and to hold the lower and upper rods in a deflected orientation when the bending force is removed from the upper and lower rods.

A vehicle seat assembly is provided with a seat back frame with an upper crossbar. A deformable member is welded to the seat back frame. A pair of tubes is welded to the deformable member. A pair of head restraint posts are each received in one of the pair of tubes to support a head restraint. A pair of spaced apart limit bracket bases is welded to the upper crossbar and extend away from the seat back frame to support a pair of limit bracket contact portions. A pair of contact target plates are each welded to one of the pair of tubes, spaced apart from and aligned with one of the pair of limit bracket contact portions so that the deformable member deforms under a rear vehicle impact until the contact target plates contact the contact portions of the limit brackets.

A guide device for a retaining rod of a headrest, having a guide structure forming a channel for guiding and supporting the retaining rod, having a latch device including a latch movable between a latching position and a release position. The latch cooperates with a latch structure of the retaining rod to prevent movement of the retaining rod relative to the guide structure in at least one direction. In the latching position the latch device is engaged with the latch structure of the retaining rod and in the release position the latch is disengaged from the latch structure. The latch device has a locking device movable between a locking position and a disengagement position and has a locking structure which, in the locking position, is in the movement path of the latch to prevent movement from the latching position into the release position and, in a disengagement position, enable movement of the latch into a release position.
