In addition, the rear side of lid 230 is formed with groove, thereby prevents that more effectively second molding part from being separated in a longitudinal direction.
Though in above-mentioned first and second embodiments, be formed on the lower surface that depression 241 on the lower surface of second molding part 240 has flat pattern, but the 3rd embodiment is owing to have said structure 241 lower surfaces with this flat pattern that therefore do not need to cave in.As a result, need not to use the front surface of guide plate 100 can safely prevent promptly that with projection 103 on the rear surface guide 200 from separating with guide plate 100.
Because manufacturing is identical with the method for second embodiment according to the method for the guide anchor that is used for safety strap of the present embodiment, therefore will omit its detailed description at this.
Can clearly be seen that from the above description according to the present invention, depression is formed on second molding part in order to be assemblied on the guide plate, allow thus to realize simply assembling and the frequency of lower appearance faulty goods by accurate molding process.
The lid eaves is extended by the bottom of lid, thereby realizes between the lid and first molding part more simply and more firm joint.
The lower end of each lid eaves all curves inwardly, and supports the lower side of second molding part, thereby prevents that second molding part from separating with lid.
The cross rib that each covers vertical end in contact of eaves and supports second molding part, thus prevent that second molding part from separating with lid in a longitudinal direction.
Lid has the latch groove that is formed on its rear side, thereby prevents that more effectively second molding part from separating with lid in a longitudinal direction.
Vertical end and second molding part of each lid eaves are cut into predetermined length, thereby prevent owing to cover the increase of the guide anchor volume that eaves causes.
When projection is formed on the surface that second molding part exposes by the friction opening that covers, projection can be when bumping because seatbelt and passenger's weight and partly damaging, thereby partly absorb bump.
When a side of second molding part stopped during with exposed state, the friction force of safety strap increased, thus more effective minimizing safety strap when bumping to the tendency of lopsidedness.
The lower surface that is recessed in of second molding part alternately is formed with projection and recessed in a longitudinal direction, and be assembled on the guide plate that alternately is formed with recessed portion and oncus, thereby allow to realize simple assembling and reduce the frequency that faulty goods occurs by the accurate molding process of firm interim joint utilization.
In addition, the projection of second molding part is longer than the oncus of guide plate, and the projection of second molding part is partly damaged when bumping thus, thereby absorbs bump.
Should be appreciated that embodiment described above and accompanying drawing are the purposes of property presented for purpose of illustration, and the present invention is only limited by claims.In addition, one skilled in the art would recognize that under the situation of the scope and spirit that do not deviate from claims and proposed, can carry out various modifications, interpolation and replacement.
