Through anchor and method of manufacture thereof
First Claim
1. A through anchor for supporting, at a vehicle, a webbing for restraining a vehicle occupant, the through anchor comprising:
- a main body portion which is formed of metal, and in which is formed an insert-through hole through which the webbing is inserted;
a piece that is assembled to a peripheral edge of the insert-through hole of the main body portion and structuring a portion of the insert-through hole, a surface of the piece being a region around which the webbing is trained, and the piece having a plurality of grooves in the surface; and
a covering portion that is molded, together with the piece, integrally at a periphery of the insert-through hole of the main body portion, and covering the periphery of the insert-through hole,wherein, among the plurality of grooves of the surface of the piece, at least the plurality of grooves at a region which is disposed at a front side of the vehicle and at an inner side of a vehicle compartment run along a direction of application of the webbing to a vehicle occupant and are formed in configurations which smoothly curve toward a rear of the vehicle, andwherein the piece has a positioning portion means for engaging with an eject pin of a mold at a time of molding the covering portion to avoid positional offset of the piece with respect to said mold.

Abstract
In a through anchor, a configuration of first grooves (or second grooves) of a region on a surface of a piece, which region is where a webbing is particularly strongly fit tightly to and slides when a vehicle rapidly decelerates (i.e., a region at a vehicle front side and a vehicle compartment inner side), runs along a direction of application of the webbing to a vehicle occupant, and is formed so as to smoothly curve toward a rear of the vehicle. Therefore, the webbing, which slides in a state of being strongly fit tightly to the first grooves (or the second grooves) on the surface of the piece, slides while a direction of sliding thereof is pulled back (corrected) toward the rear of the vehicle.

21. A method of manufacturing a through anchor which is for supporting, at a vehicle, a webbing for restraining a vehicle occupant, the method comprising:
-
fabricating a main body portion of a through anchor which is formed of metal and has a through hole; fabricating a piece having a surface around which the webbing is trained, and a member extending away from the surface that includes a positioning portion for engaging eject pins of a mold; forming a plurality of grooves, which run along a direction of application of the webbing to a vehicle occupant and which smoothly curve toward a rear of the vehicle, at least at a region of the surface of the piece which region is disposed at a front side of the vehicle and at an inner side of a vehicle compartment; assembling the piece to a peripheral edge of the through hole of the main body portion; molding a covering portion, together with the piece, integrally to a periphery of the through hole of the main body portion, the covering portion covering the periphery of the through hole, so as to form an insert-through hole through which the webbing is inserted, wherein at the time the covering portion is molded, the positioning portion engages eject pins of a mold to avoid positional offset of the piece during molding. - View Dependent Claims (22)
