Abstract

To simplify a retractor fitting structure for seat belt provided below a parcel shelf at the rear section of a vehicle. A bracket 5 is connected to the lower face of a parcel shelf 4, and an anchor bolt 6 fitted with an anchor ring 7 inserted with a seat belt 2 is screwed to a nut 5c deposited to the bracket 5. A suspension section 5a extended downward is formed on the bracket 5, a retractor 3 is fitted to the suspension section 5a, and the retractor 3 is arranged below the parcel shelf 4 in the cantilever state.

Description

The supporting structure of seat frenulum constrictor

The present invention relates to a kind of supporting structure that is mainly used on the seat frenulum constrictor that the power car back seat uses.Specifically, it relates to a kind of supporting structure that is located at the seat frenulum constrictor below the smallclothes frame behind this car rear portion.

Traditional way is, when below constrictor being located at the smallclothes frame, often adopts following layout.Promptly on the power car car body, fixedly install one and be positioned at lower bracket below the upper bracket with smallclothes frame lower surface bonded assembly upper bracket and one.Constrictor is contained on the lower bracket and is tightened onto on the upper bracket by the smallclothes frame with a tie bolt.From the seat frenulum that constrictor is drawn be pulled to the top, by being located at perforated window on the smallclothes frame then by an anchor ring that is contained on the tie bolt.

When being retracted device locking, frenulum have a power of upwards drawing to be applied on the lower bracket by constrictor.In above-mentioned traditional arrangement, on a fixed position, be welded with a reinforcement, lower bracket is fixed on the car body so that bear this pulling force.Thereby but this assembling more manpower increase of palpusization expense expense during power car that is arranged in.

Because the above-mentioned shortcoming of traditional arrangement the objective of the invention is to make the better simply constrictor of structure to obtain support intensity.

In order to achieve the above object, the present invention one is located at the supporting structure of the seat frenulum constrictor below the smallclothes frame of power car rear portion, and said supporting structure comprises: a support that is connected on the smallclothes frame lower surface; One is tightened on tie bolt on the said support by the smallclothes frame, makes the frenulum of drawing from constrictor be pulled to the top and is provided with perforated window on the smallclothes frame then by an anchor ring that is contained on the said tie bolt by one; Wherein on said support, form a part of extending downwards and constrictor is arranged on below the smallclothes frame with cantilevered fashion so that constrictor is contained in.

When the seat frenulum is locked, have a thrust that makes progress by constrictor effect (or applying) on support.But also apply a downward pulling force simultaneously by tie bolt.Therefore the thrust that makes progress is by downward pulling force payment, and the result is not applied on the connecting portion between support and the smallclothes frame with regard to there being undue power.Therefore constrictor can obtain installation strength and can not need special (or special) enhancing.Thereby traditional lower bracket just can no longer need, and expense just can greatly reduce like this.

Fig. 1 is one embodiment of the present of invention, and part is with the lateral plan shown in the section.

Illustrated embodiment is exactly that the present invention is applied to a kind of layout on the supporting structure of constrictor 3 of seat frenulum 2 of back seat 1 of power car.Constrictor 3 be set at the power car rear portion smallclothes frame 4 below.

There is support 5 usefulness spot welding or the similar approach with downward extension that its upper end curve 5b is connected on the lower surface of smallclothes frame 4 to lower extension 5a.There is a nut 5c to be welded on the lower surface of curve 5b.There is a tie bolt 6 to be tightened onto in the nut 5c by smallclothes frame 4.Also have a frenulum of drawing to be pulled to the top, by a perforated window 4a who on smallclothes frame 4, forms, then by an anchor ring 7 that is contained on the tie bolt 6 from constrictor 3.In the present embodiment, have lid 8 usefulness tie bolts 6 that cover perforated window 4a to be installed on the smallclothes frame 4, and seat frenulum 2 is arranged the guide hole 8a by a formation on lid 8, enters then in the anchor ring 7.In the drawings, label 9 is depicted as a back pad that is arranged on the smallclothes frame 4.

Constrictor 3 usefulness one bolt of rear end plate 10 be contained in support 5 on the front surface of lower extension 5a, this bolt is screwed in the nut 5d who is welded on the rear surface of the bottom of lower extension 5a.Constrictor 3 just is arranged on following (promptly be provided with in the mode that hangs and does not support together the lower end to lower extension 5a of support 5) of smallclothes frame 4 in the mode of cantilever like this.When rotational fixation bolt 10 tightens up constrictor 3, rotate in order to prevent constrictor 3, making a claw piece 3a on the constrictor 3 so that be used for and engage at the conjugate foramen 5e that on lower extension 5a, forms.

When with 2 lockings of seat frenulum, there is a thrust that makes progress to be applied on the support 5 by constrictor 3.But this thrust that makes progress is offset by the downward pulling force that applies by anchor ring 7 and tie bolt 6, and the result does not just have undue power and executes on the connecting portion of support 5 and smallclothes frame 4.In addition, be shaped on crooked flange 5f, 5g (in the drawings, only illustrate in this two flange one) respectively along the side to the side of lower extension 5a and upper end curve 5b of support 5.These two flange 5f, 5g indicate in Fig. 1 on the part of " A " with spot-welded on, thereby increase the bending stiffness to lower extension 5a.So just can prevent the bending that causes owing to the vertical compression effort that acts on lower extension 5a during frenulum 2 in locking to lower extension 5a.

Claims

1. supporting structure that is arranged on the seat frenulum constrictor (3) below the power car rear portion smallclothes frame (4), said supporting structure comprises:

One and smallclothes frame (4) lower surface bonded assembly support (5);

One is tightened onto tie bolt (6) on the said support (5) by smallclothes frame (4), make the seat frenulum (2) of drawing from constrictor (3) be pulled to the top, by one be arranged on perforated window (4a) on the smallclothes frame (4), then by an anchor ring (7) that is contained on the said tie bolt (6);

Wherein go up forming one at said support (5) is arranged on below the smallclothes frame (4) with cantilevered fashion so that constrictor (3) is contained in the said constrictor (3) that makes on lower extension (5a) to lower extension (5a).
