摘要： A vehicular seat capable of effectively mitigating lateral direction vibrations is provided. In the present vehicular seat (10), a pair of leg portions (32A) of a headrest frame (32) are coupled to a seatback frame (20) to be relatively turnable about a longitudinal direction axis of a seatback (18). Joint portions 32C are provided between the pair of leg portions (32A) and a middle portion (32B) of the headrest frame (32). Thus, the headrest (14) is made turnable to left and right with respect to the seatback (18). Furthermore, the headrest (14) is urged toward a middle position of the range of turning with respect to the seatback (18) by rubber members that are provided between a headrest support (24) and a support bracket (20C). Thus, when lateral direction vibrations are applied to the present vehicular seat (10), the headrest (14) functions as a dynamic damper.

摘要： An operation cable (40) has an operational structure in which an inner member (41) inserted into a tubular outer member (42) is pulled from a lower end side thereof. The operation cable (40) having a double layer structure is axially connected to a double layer cable that is constructed from a stay (4B) of a headrest (4) and a push rod (50) inserted into the tubular stay (4B). In particular, the stay (4B) is inserted into a support (2S) positioned on an upper portion of the seat back (2), a lower end of the stay (4B) and an upper end of the inner member (41) are axially connected to each other, so that a lower end of the push rod (50) in the tubular stay and a head portion (42H) of the outer member (42) are positioned closer to each other. As a result, the push rod (50) can be pushed by the head portion (42H) of the outer member (42) when the operation cable (40) is pulled.

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.
