Abstract

A face image obtained by imaging a vehicle occupant by a CCD camera (10) is recorded in an image memory (140). A CPU (170) detects the position and the direction of a face of the occupant according to the face image recorded in the recording memory (140). The CPU (170) is triggered by an input from an obstacle detection sensor (60) to calculate a displacement amount and a rotation amount of a headrest (200) according to the face and the direction of the face of the occupant against the headrest (200) and the direction and the speed of the obstacle against the vehicle and adjust the position and angle of the headrest (200) by driving a motor (211).

Description

technical field [0001] The invention relates to a headrest adjusting device and method for adjusting the position and angle of the headrest. Background technique [0002] Patent Document 1 discloses, as a device for adjusting the position of a vehicle seat, for example, a technique for detecting a three-dimensional position of an occupant for adjusting the posture of the seat or adjusting the position of the seat at the time of a vehicle collision. In addition, Patent Document 2 discloses a method and an apparatus for detecting a three-dimensional position of a vehicle occupant. [0003] Patent Document 1: (Japanese) Special Publication No. 2006-513859 [0004] Patent Document 2: (Japanese) Special Publication No. 2006-510076 [0005] The device for adjusting the shape of a vehicle seat disclosed in Patent Document 1 changes the shape of the seat using a signal of non-contact measurement induction that reliably captures and detects the posture of an occupant. [0006] How...
