Abstract

A headrest which supports a head portion of a passenger in a vehicle rear collision is attached to an upper portion of a frame of a seatback. A blower to perform ventilation for a passenger's back is arranged at the upper portion of the frame at a position below the headrest. The blower is held at the frame via attaching members, for example. When receiving a large rearward-load from the passenger in the vehicle rear collision, the blower moves rearward relatively to the frame and the headrest according to a rearward move (a rearward swing around an upper frame, particularly) of the attaching member and the like.

First claim

What is claimed is:

1 . A seat structure of a vehicle provided with a seatback, to an upper portion of which a headrest is attached and a back face of which has a vent portion, wherein:
a blower to perform ventilation through the vent portion is arranged at an upper portion of the seatback at a position below the headrest; and said blower is configured to be movable rearward relatively to a frame of the seatback and the headrest when receiving a large rearward-load from a passenger seated in the seat in a vehicle rear collision.

2 . The seat structure of the vehicle of claim 1 , wherein said frame of the seatback comprises an upper frame which extends in a width direction of the vehicle and to which said headrest is attached, and said blower is supported at said upper frame such that a rearward-move amount of a lower portion of the blower is greater than that of an upper portion of the blower when receiving the large rearward-load from the passenger in the vehicle rear collision.

3 . The seat structure of the vehicle of claim 2 , wherein said blower is supported at the upper frame so as to swing rearward around the upper frame.

4 . The seat structure of the vehicle of claim 3 , wherein there is provided an attaching member, an upper end portion of which is rotatably attached to said upper frame and which comprises a downward extension portion extending downward from the upper frame, and said blower is attached to said downward extension portion.
