Seatbelt Through-Anchor And Seatbelt Device

摘要

The present invention provides a seatbelt through-anchor and device capable of preventing jamming during an emergency. A through-anchor is rotatably attached to a vehicle interior wall and is folded back after a webbing extracted from a retractor is inserted through the through-anchor. The through-anchor includes: an insertion hole including an approximately linear lower edge on which the webbing slides, and a lateral edge curving from an end part of the lower edge; a lower-side part provided below the lower edge; and a bump part extending from an end of the lower-side part, protruding beyond a surface of the lower-side part in a direction corresponding to a vehicle interior side. The bump part includes peak parts protruding the furthest in the course of separating from the lateral edge, and includes, between each of the peak parts and the lateral edge, a first sliding surface including a curved surface outwardly protruding from the through-anchor.

主权项

1. A seatbelt through-anchor which is rotatably attached to a vehicle interior wall and which is folded back after a band-shaped webbing extracted from a retractor is inserted through the seatbelt through-anchor, the seatbelt through-anchor comprising:
an insertion hole through which the webbing is inserted, the insertion hole including an approximately linear lower edge which comes into contact with a surface of the webbing so as to traverse the webbing and on which the webbing slides, and a lateral edge extending in a curve from an end part of the lower edge; a lower-side part provided below the lower edge; and a bump part provided on a surface of the through-anchor so as to extend from a vicinity of an end of the lower-side part in a lateral direction of the through-anchor and protruding beyond a surface of the lower-side part in a direction corresponding to a vehicle interior side when the through-anchor is installed, wherein the bump part includes peak parts protruding the furthest in the course of separating from the lateral edge, and the bump part includes, between each of the peak parts and the lateral edge, a first sliding surface including at least a curved surface outwardly protruding from the through-anchor which comes into contact with a surface of the webbing and on which the webbing slides.
