Description
Technical field
The utility model relates to a kind of sliding rail for vehicle seat, is used for belonging to the vehicle body fittings technical field to the lengthwise position adjustment of automotive seat and to adjusted locking position.
Background technology
Industry is all known, as sliding rail for vehicle seat, mainly contain three big component set-ups, it is the blocking device that the upper rail and the lower guideway of both mutual bearing fits and being used for locks upper rail and lower guideway, be no lack of in patent documentation and be seen in such structure, the applicant's contriver formerly also applies for having multinomial about sliding rail for vehicle seat.Yet, make a general survey of the sliding rail for vehicle seat in the prior art, its blocking device all is to show as monolateral locking, promptly offer and be used for the emissions groove that the tooth on the confession lockplate of blocking device stretches in any side of guide rail, representational example such as Chinese patent Granted publication CN1081560C, though this patented technology scheme can be eliminated the shortcoming of US4964608 and the disclosed scheme of DE3935359: when blocking device stressed when big, though can prevent to lock tooth throws off from the notch of the fixed part of slide rail, and after power stopped, strained tooth can be deviate from from notch.In view of the above, CN1081560C improves blocking device, make the tooth of blocking device be parallel to direction of slip well and also therefore be parallel to notch in a row and extend, use the notch engagement that guarantees all teeth and fixed parts (specification sheets the 4th page go along the several the 4th to the 5th).Yet, make a general survey of the instruction of this patented technology scheme, because it adopts the upper rail (patent claims moving-member) and the locking of lower guideway (patent claims fixed parts) the monolateral locking of blocking device equally, therefore, only can alleviate the lock tooth danger of deviating from, and can not solve the distortion problem behind the impulsive force that is particularly happened suddenly after stressed from the emissions groove mouth; Therefore hidden danger is hidden all the time.The applicant has also obtained private observed data to the locking reliability of the sliding rail for vehicle seat of present monolateral latch-up structure there from car production manufacturer, and test results is very disappointed.Along with the further raising of people to vehicle complete vehicle safety understanding, seat is much accounted of too with the safety of slide rail, therefore is necessary to be improved.
Again, the adjustment step pitch of present sliding rail for vehicle seat is big, and about 15-20mm degree causes therefrom and can't satisfy the driving staff and want the optimal comfort degree that reaches.
And, existing sliding rail for vehicle seat since ball the shortage reasonableness is set, losing efficacy easily in therefore stressed back, influences the mobile effect of upper rail and even can't move.
Summary of the invention
Top priority of the present utility model is to provide the locking of a kind of blocking device reliably, can not occur using and guaranteeing safe sliding rail for vehicle seat because of the stressed torsional deflection that causes.
Another task of the present utility model is to provide a kind of can making to adjust step pitch and satisfy to the driving staff and want the sliding rail for vehicle seat of the optimal comfort degree that reaches.
An also task of the present utility model is to provide a kind of ball to be provided with and rationally uses the sliding rail for vehicle seat of avoiding stressed inefficacy.
For top priority of the present utility model is finished in embodiment, technical scheme provided by the utility model is: a kind of sliding rail for vehicle seat, comprise that one is used for the upper rail that connects with automotive seat, one is used for the lower guideway that connects with car floor, one is arranged at the roller stand in the lower guideway, and one be configured in by last, the lower guideway cunning is joined the blocking device that being used in the common cavity volume that constitutes of back institute locks upper rail and lower guideway, constitute to the bilateral symmetry of upper rail a pair of spherical guide, spherical guide is provided with ball registration roller and first, second ball, be provided with the locking emissions groove between on the lower guideway, and two upper lateral parts of lower guideway bend in opposite directions and constitute a pair of be used to hold described ball registration roller and first, the guide-track groove of second ball, characteristics are: be located at the bottom of lower guideway between described locking emissions groove, offer and lock the corresponding guide groove that is used for supplying described blocking device to see through and locks at locking emissions groove place in position of emissions groove on the described roller stand.
Finish another task of the present utility model for embodiment, technical scheme provided by the utility model is: the step pitch between the described locking emissions groove is 9-11mm.
Finish an also task of the present utility model for embodiment, this with the bright technical scheme that is provided is: the quantity of described first ball is a pair of.
In an embodiment of the present utility model, be located at the position placed in the middle of the bottom of lower guideway between described locking emissions groove.
In another embodiment of the present utility model, described step pitch is 10mm.
In also embodiment of the present utility model, described step pitch is self aperture of locking emissions groove and the summation of the spacing distance between the adjacent locking emissions groove.
In another embodiment of the present utility model, described aperture is 5mm, and described spacing distance is 5mm.
In another embodiment of the present utility model, described blocking device comprises the locking seat in tool seat chamber, adapter sleeve, depression bar, lockplate, spring, respectively extended a fixing feet on the chamber wall body in the seat chamber of locking seat, fixing feet is fixed by means of the fixed orifice and the upper rail that are preset on the upper rail, one end of adapter sleeve and depression bar links, the nearly middle part hub setting of depression bar is at an end of locking seat, and in described seat chamber, narrow the contracting of the other end of depression bar has a depression bar gib head, the depression bar gib head matches with the locking wrench of lockplate one end and acts on the locking wrench, the lockplate hub setting is at the other end of locking seat, and in the seat chamber, be provided with between the below of the other end of lockplate and be used for locking the lock tooth of joining mutually with described locking emissions groove, the two ends of spring are separately fixed on depression bar and the lockplate.
In another embodiment again of the present utility model, the quantity of described lock tooth has two at least, and the tooth pitch between the lock tooth is to equate with the slot pitch of locking emissions groove.
In also another embodiment of the present utility model, be concaved with the first jump ring groove on the described depression bar, and be concaved with the second jump ring groove on the described adapter sleeve, the position of first, second jump ring groove corresponds to each other and is provided with jump ring.
The utility model is by the advantage of above-mentioned disclosed technical scheme: owing to will lock the bottom that emissions groove is opened in lower guideway, therefore can obtain desirable and the locking effect coupling mechanism force balance, the emissions groove distortion can not occur locking, be out of shape, can demonstrate fully safety; Because the slot pitch of locking between the emissions groove is provided with rationally, step pitch only be 9-11mm, therefore can satisfy the driver and passenger seat position is done the fine setting requirement of forward and backward adjustment, uses the comfort level of acquisition the best; Because therefore the preferred quantity of first ball can avoid first ball because of stressed short term failure.
