Patent ID: 7931331

Claim:
A headrest for mounting on one or more vertically extending posts positioned on the backrest of a front seat of a vehicle, the headrest comprising: a) one or more mounting sleeves positioned on the headrest and adapted to surround a portion of a respective one of said posts; b) a pivot means extending between each mounting sleeve and the respective post to mount said mounting sleeve on the respective post in pivotal relation thereto about a pivot axis substantially transverse to the longitudinal axis of the post; c) each said mounting sleeve being shaped and otherwise dimensioned on an internal surface to interact with said respective post to resist pivotal movement of the headrest between first and second pivot positions below application of a directed threshold force to the headrest by a rear passenger onto a rear surface of the headrest, wherein each of said mounting sleeves frictionally interact with the respective post in a region adjacent to the pivot means so as to resist said pivotal movement, wherein said one or more mounting sleeves each comprise at least a first sleeve portion contiguous with a second sleeve portion with said first sleeve portion shaped and otherwise dimensioned to surround and retain an initial portion of the post in contacting relation when the headrest is in said first pivot position, and with said second sleeve portion shaped and otherwise dimensioned to surround and retain a final portion of the post in contacting relation when said headrest is in said second pivot position, wherein the post is cylindrical, said first and second sleeve portions have substantially semi-circular cross-sections defining a first sleeve axis and a second sleeve axis respectively, wherein said first sleeve axis is aligned with the longitudinal axis of the post when the headrest is in said first pivot position, and wherein said second sleeve axis is aligned with the longitudinal axis of the post when the headrest is in said second pivot position, wherein said one or more mounting sleeves are shaped and otherwise dimensioned to resist said pivotal movement by means of a waisted portion formed at a junction of said first sleeve portion and said second sleeve portion, and further comprising one or more energy absorption recesses positioned in adjacent relation to said waisted portion to allow flexion of said waisted portion upon said interaction with the respective post.
