A vehicle seat trim assembly for concealing a vehicle seat frame is provided with at least two adjacent panels, which are oriented at angles relative to each other. At least one slot extends through the at least two adjacent panels. An interior lining is formed from a flexible nonwoven fabric material and sewn within the at least one slot. The interior lining includes a slot with a width smaller than the width of the at least one slot in the at least two adjacent panels to enclose the slot in the at least two adjacent panels and to deform to provide clearance for a head restraint post. An embroidered seam is sewn into the vehicle seat trim member around the at least one slot and sewn into the interior lining to attach the interior lining to the at least two adjacent panels.

A vehicle seat assembly is provided with a seatback frame adapted to be mounted to a vehicle interior. The seatback frame has a front region facing a forward direction, and a rear region. A first bracket is mounted to the front region of the seatback frame. A second bracket is mounted to the first bracket and the rear region of the seatback frame. At least one head restraint post is mounted to the first bracket or the second bracket and spaced apart from the seatback frame so that upon a rear vehicle impact, the second bracket deforms as the at least one head restraint post is translated toward the seatback frame.

A support rod for a vehicle seat head restraint, which is formed as a tube, having at least one structure as part of a locking device and intended for cooperating with a catch of the locking device which is associated with a holding structure. The structure has a base surface which prevents movement of the catch radially to a central axis of the support rod and includes a catch surface that prevents, together with the catch, movement of the support rod in a first direction. At least one catch structure as a detent structure has a cut-out tongue. An inner surface of the tongue radially facing a central axis of the support rod at a free end being spaced apart from the base surface by a height so that the catch is movable at least with a partial region radially under a region of the inner surface of the tongue.

A vehicle seat assembly is provided with a seat back frame. A bracket is provided with a substrate welded to the seat back frame. Two pairs of sidewalls extend from the substrate and are tapered with an enlarged region at an upper distal end. A pair of support plates are each supported by one of the two pairs of sidewalls and spaced apart from the substrate to provide a mounting surface. A pair of spaced apart tubes are each welded to the bracket mounting surface of one of the pair of support plates. A pair of head restraint posts are each received in one of the pair of tubes. A head restraint is supported upon the pair of head restraint posts, so that upon a rear vehicle impact, the bracket deforms as the pair of head restraint posts are translated toward the seat back frame.

A headrest support structure has an upper panel, a collar and a sleeve. The upper panel extends in a width direction of a seatback frame at the upper part. The upper panel has a sleeve support part including upper and lower wall parts facing in a direction perpendicular to the width direction. The sleeve support part is in a U-shape open to a side opposite to a seating side in a longitudinal sectional shape. The upper and lower wall parts have upper and lower holes. The collar is in a tubular shape with a through hole. The collar is arranged between the upper wall part and the lower wall part to have the through hole communicate with the upper and lower holes. The sleeve is inserted through the upper hole, the through hole, and the lower hole. A rod-like leg portion of a headrest is insertable in the sleeve.

A sliding sleeve (6, 60) for fixing in a securing support (5, 50). The sliding sleeve (6, 60) includes a sleeve body (6.2, 60.2) with a coupling section (6.3, 60.3) with at least one flexible coupling face (6.4, 60.4) for bearing against the securing body (5, 50).

A vehicle seating assembly is disclosed herein. The seating assembly includes a head restraint having a post. A seatback is configured to receive a portion of the post. The stop feature is coupled to the seatback and is movable between a disengaged position and an engaged position. In the engaged position, the stop feature is configured to generally prevent inward movement and allow outward movement of the post relative to the seatback.
