Abstract

The present invention has a simple configuration and shortens the time it takes for a headrest to contact a passenger's head in the event of a rear impact. In a seat device, a stay (46) (comprising a grommet (22)) is set to have lower bending rigidity in the forward direction of the vehicle than in the rearward direction of the vehicle. Because of this, if the headrest oscillates when the vehicle suffers a rear impact, the headrest temporarily shifts in the rearward direction of the vehicle and then reverses after a short amount of time and begins shifting in the forward direction of the vehicle. Furthermore, since the bending rigidity of the stay (46) (comprising a grommet (22)) in the forward direction of the vehicle is less than the bending rigidity of the stay in the rearward direction of the vehicle, the headrest shifts to a large degree in the forward direction of the vehicle. In this way, the time it takes the headrest to come into contact with the head (H) of the passenger can be shortened. Moreover, setting the bending rigidity of the stay (46) that comprises the grommet (22) makes it possible for the headrest to be immediately shifted toward the head (H) of the rider, so the time it takes the headrest to come into contact with the head of the rider can be shortened by means of a simple configuration.

Description

technical field [0001] The present invention relates to a vehicle seat provided with a headrest for supporting the head of an occupant. Background technique [0002] In the automotive seat described in Patent Document 1 below, a shock-receiving frame is disposed in front of a seatback frame, and a lower end portion of the shock-receiving frame is fixed to the seatback frame. The upper end portion of the impact-receiving frame is joined to a headrest support frame that supports the headrest, and the headrest support frame is rotatably supported by the seat back frame via a rotating member. [0003] In the event of a rear impact of the vehicle, the head restraints are moved (displaced) forward (so-called "active head restraints"). As a result, the occupant's head is restrained by the headrest, and whiplash damage to the occupant is suppressed. [0004] However, it is preferable to directly restrain the head of the occupant who moves toward the rear of the vehicle due to iner...
