Title:
HEADREST SUPPORT STRUCTURE
Document Type and Number:
Japanese Patent JP2014008335
Kind Code:
A
Abstract:
To provide a headrest support structure which enables more accurate setting of a resonance frequency of a seat relative to forward and backward vibrations.
When a tilt amount of headrest stays 14L, 14R in a front-back direction of a seat relative to a seat back frame 10 is within a stipulated range, the headrest stays 14L, 14R are supported such that support rigidity of a headrest 13 relative to the front-back direction of the seat is reduced compared to a case when the tilt amount is outside the range. The two right and left headrest stays 14L, 14R are coupled so as to be relatively swingable in the front-back direction of the seat in the headrest 13.
