摘要： In a conventional active headrest device, in order to protect a head etc. at the time of collision, a headrest ascends, and an ascent stroke is secured. However, it was proven that this construction is a little unsatisfactory in terms of ascent speed or distance in following the movement of a head, etc. at the time of the collision. Further, it is considered that this ascent speed or distance incurs a risk of a second accident and causes a new problem. In light of the above circumstance, the active headrest of the invention includes individual means provided in a seat back. The individual means includes a lower unit which operates by an impact given to a frame, a wire which elevates/lowers inside the seat back linked to the lower unit, a solenoid to which the wire is locked and/or an upper unit having the solenoid, and a headrest device linked to a lifter or a connecting portion of the upper unit. At the time of collision, the wire is tensioned downward, the lifter or connecting portion of the upper unit ascends or tilt forward, and the ascent and forward tilting of the headrest are performed instantaneously. As a result, this headrest can secure the ascent stroke and forward tilting which can follow the movement of a head, etc. at the time of collision, and can protect a head, etc.

摘要： The headrest support is constituted of an approximately umbrella-like head portion (100), a neck portion (101) and an approximately cylindrical barrel portion (102) arranged below the neck portion. A stay-and-receiving-member pressing portion (13) having resiliency is formed by forming a first cut groove (1300) in an intermediate portion of the barrel portion and by setting the stay-and-receiving-member pressing portion free in at least two directions from the barrel portion. The stay-and-receiving-member pressing portion is formed in an arcuate shape as viewed in a cross section, wherein a curved inner surface (1301a) is formed at a center portion of a curved inner surface, and a projecting outer surface (1302) which projects toward the receiving member side is formed on a curved outer surface end portion. And one or plural pairs of resilient members (8) are respectively formed on an upper portion and an intermediate portion of the barrel portion. An outer peripheral portion of the stay (3) is pressed by the curved inner surface (1301a) and an inner surface (6c) of the receiving member (6) is pressed by the projecting outer surface (1302) and/or the respective pairs of the resilient members (8).

摘要： The headrest support is constituted of an approximately umbrella-like head portion (100), a neck portion (101) and an approximately cylindrical barrel portion (102) arranged below the neck portion. A stay-and-receiving-member pressing portion (13) having resiliency is formed by forming a first cut groove (1300) in an intermediate portion of the barrel portion and by setting the stay-and-receiving-member pressing portion free in at least two directions from the barrel portion. The stay-and-receiving-member pressing portion is formed in an arcuate shape as viewed in a cross section, wherein a curved inner surface (1301a) is formed at a center portion of a curved inner surface, and a projecting outer surface (1302) which projects toward the receiving member side is formed on a curved outer surface end portion. And one or plural pairs of resilient members (8) are respectively formed on an upper portion and an intermediate portion of the barrel portion. An outer peripheral portion of the stay (3) is pressed by the curved inner surface (1301a) and an inner surface (6c) of the receiving member (6) is pressed by the projecting outer surface (1302) and/or the respective pairs of the resilient members (8).
