At last, Webbing retractor 10 is directly installed on the below of back clothing plate 11, and the client opens luggage-boot lid and just can see, from visually-perceptible qualitatively, also has apparent defect attractive in appearance inadequately.

The utility model content

The purpose of this utility model is, overcome the defective of above-mentioned prior art and provide a kind of under the prerequisite that satisfies the Webbing retractor installation requirement, can improve the car load torsional stiffness effectively, reduce Material Cost, avoid simultaneously exposing the later-model vehicle safety belt mounting arrangement of furl apparatus that causes the visually-perceptible quality problems because of Webbing retractor.

For achieving the above object, the utility model is taked following design plan:

A kind of later-model vehicle safety belt mounting arrangement of furl apparatus of the present utility model comprises back clothing plate, back of seat crossbeam and Webbing retractor, and described Webbing retractor is arranged in the cavity that forms between described back of seat crossbeam and the described back clothing plate.

Preferably, described cavity in the size of vehicle fore-and-aft direction greater than described Webbing retractor size.

Preferably, be provided with opening on the clothing plate plate of described back, described opening is arranged on the anterior inclined-plane of described back clothing plate.

Preferably, the size of described opening is greater than the size of described Webbing retractor.

Preferably, described Webbing retractor is bolted on the clothing plate of described back by one.

Preferably, the rear side of described Webbing retractor is provided with adapter plate, and described bolt is mutually permanently connected by adapter plate and Webbing retractor.

The utility model has the advantages that: because Webbing retractor of the present utility model has been installed in the cavity, the back border (vertical plane) of back of seat crossbeam no longer is restricted, thereby can move backward to increase the torsional stiffness that cavity cross-sectional area improves car load as required.Simultaneously, because Webbing retractor is surrounded by cavity, can't see taking-up device body lofty in the mode two when the client opens trunk lid, thereby improve single-piece visually-perceptible quality.
