FRAME STRUCTURE OF SEAT BACK

摘要

PROBLEM TO BE SOLVED: To provide a frame structure capable of preventing slackening and positional dislocation of webbing of a seat belt device for passing the webbing through the back face side of a seat back. SOLUTION: A child seat anchor wire 30 is arranged in a lower part of a seat back frame 10. The child seat anchor wire 30 is provided with base parts 31 and 32 fixed to a lower frame material 13, a pair of left and right guide parts 33 and 34 and a crossbar part 35 for connecting the tips of the guide parts 33 and 34. The guide parts 33 and 34 extend forward from the lower side of the lower frame material 13. The webbing 22 delivered from a retractor 21 of the seat belt device 20 passes between the under surface side of the crossbar part 35 and the guide parts 33 and 34, and turns upward along a back face from the lower part of the seat back frame 10. This webbing 22 is pulled out to the front face side of the seat back frame 10 by passing through a belt ring 23.
