Abstract
The utility model relates to a peel strength enhancing device for the sliding rail of a car seat, a seat sliding rail and an enhancing baffle plate, wherein the peel strength enhancing device for thesliding rail of a car seat comprises the enhancing baffle plate arranged in the lower rail of the sliding rail. The utility model is characterized by further comprising an opening formed on the lateral wall of the sliding rail, a hook profile is arranged at the top end of the baffle plate, and the hook profile at the top end of the baffle plate is engaged with the opening after the upper rail of the sliding rail is deformed and folded.
Description
Technical field
The utility model relates to a kind of intensifier of peel strength of seat slide, and it is included in the reinforcement catch of captive joint in the following rail of slide rail, and this last rail of strengthening catch and the slide rail of distortion is coupled and the peeling force of enhancing slide rail.
Background technology
The test of automobile safety seat belt fastened point intensity is the harsher mandatory safety test that automotive seat must pass through.Various countries all formulate this test test requirement specification, as Chinese GB14167-1993, and European ECE 14, U.S. FMVSS 210 etc.Especially when seat moves to rearmost end, because being in down outside the rail rear end, the last rail rear end part length of slide rail when stressed, can not be contained by rail down, make the strained condition deterioration.
For strengthening the slide rail peel strength that last rail rear end part length is in situation outside the following rail rear end, solution commonly used mainly contains two kinds.
A kind of typical way is to increase by an anti-deformation block of peeling off in last rail cross section.During the belt anchorage point strength test, load reaches screw by safety strap by the safety strap fixed support, thus the U-shaped of projection welding in last rail anti-peel off deformation block in order to limit the rail distortion improve about the engagement situation of rail to improve its peeling force.Adopt this kind slide rail peel strength to strengthen the slide rail of mode, its peeling force only relies on the engagement situation of rail up and down, and the transmission of power reaches down rail wing limit by last rail wing limit fully and reaches vehicle body by the slide rail bolt of rear end plate then.
Another kind of typical way is to increase by one to peel off the reinforcement catch in following rail cross section.On the rail, catch had enough gaps not influence slip with last rail inside face when sliding before and after seat is normal under catch was fixed in the riveted joint mode, but when the belt anchorage point strength test, this catch promptly plays the effect that slide rail is peeled off reinforcement.The most of engagement situation of rail up and down that relies on of this kind solution slide rail peeling force, most of power reaches down rail wing limit by last rail wing limit and reaches vehicle body by the slide rail bolt of rear end plate then, thus in addition last rail distortion draw in tooth position, catch top, back more can by with last rail in wall friction or thrust the rail inwall thus also can share a part of power also directly be passed under rail make peeling force higher.This catch requires very high to tooth functional areas, top, must adopt smart dashing obtaining correct leading dimensions and roughness of surface requirement, and these tooth functional areas, catch top must be heat-treated to obtain high hardness so that it can effectively thrust the rail inwall to play the effect that peeling force is strengthened when strength test.Thereby this catch cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of seat (especially automotive seat) slide rail peel strength intensifier, seat slide and strengthens catch, and this seat slide peel strength intensifier reduces the requirement of strength of catch functional areas.
In order to realize described purpose, the peel strength intensifier of the slide rail of automotive seat of the present utility model, comprise the enhancing catch in the following rail that is arranged on slide rail, be characterized in, also be included in the opening of the sidewall formation of slide rail, the top of this catch has the hook-type profile, and the last rail of slide rail is after distortion is drawn in, and the hook-type profile on the top of catch and this opening mesh.
The peel strength intensifier of the slide rail of described automotive seat, its further characteristics are that this opening is a rectangular opening.
The peel strength intensifier of the slide rail of described automotive seat, its further characteristics are that four jiaos of this rectangular opening with round-corner transition.
The peel strength intensifier of the slide rail of described automotive seat, its further characteristics be, is formed with a plurality of described openings symmetrically in the two side of slide rail, and the bilateral symmetry ground on the top of this enhancing catch forms states the hook-type profile to some extent.
The peel strength intensifier of the slide rail of described automotive seat, its further characteristics are the following rail riveted joint of described catch slide rail.
For realizing described purpose, the peel strength of sliding rail of automobile seat of the present utility model strengthens catch, comprises catch body and the functional areas that form in the upper end of catch body, is characterized in, described functional areas are the hook-type profiles that form in the upper end of catch body.
For realizing described purpose, sliding rail of automobile seat of the present utility model comprises rail and following rail, and last rail slides in descending rail, it is characterized in that, is formed with the functional areas ingear opening that is used for described peel strength catch at the sidewall that descends rail.
Described seat slide, its further characteristics be, described opening is a rectangular opening, and four jiaos of this rectangular opening all with round-corner transition.
The peel strength intensifier of the slide rail of aforementioned automotive seat also can be used for the slide rail of other field, to strengthen its peel strength.
The beneficial effects of the utility model are: the slide rail peel strength is strengthened the used catch of solution and just can be coupled with last rail owing to need not to thrust rail, thereby adopts common diel to make, and do not need heat treatment, thereby cost is lower.

The specific embodiment
To shown in Figure 6, sliding rail of automobile seat comprises rail 1 and following rail 2 as Fig. 1, and following rail 2 is connected on the automotive floor panel by screw 4, and last rail 1 is by screw 5 attachment security band fixed supports (not showing).Riveted joint has the catch 7 of enhancing in the following rail 2, and the sidewall of last rail 1 is formed with a plurality of rectangular opening 1a.The both sides that strengthen the top of catch 7 have symmetrical hook-type profile 7a.In belt anchorage point strength test process, after last rail 1 distortion, strengthen the hook-type profile 7a of catch 7 and all shape hole 1a engagements.
The hook-type profile 7a that strengthens the top of catch 7 is its functional areas.The length of rail 2 rear ends was determined under upward departed from rail 1 rear end when the quantity of rectangular opening 1a was adjusted to the rearmost position according to seat.Four jiaos of rectangular opening 1a all with round-corner transition.
Leave enough gaps at catch 7 and last rail 1 inside face, do not slide so catch 7 does not influence the normal front and back of seat.Its slide rail is peeled off and is strengthened principle of work as shown in Figure 7.When the belt anchorage point strength test, last rail 1 is out of shape gathering after being subjected to pulling force, thereby the rectangular opening of the hook-type profile on the top of catch 7 and last rail 1 engagement transmitted load plays the effect of sharing and strengthening peeling force.
