Abstract

The utility model relates to a slide rail for a vehicle seat. The slide rail comprises a slide core, a slide shell and a plurality of steel balls. The slide rail is characterized in that the lower end of the vertical folding partition of the slide core is an arc folding partition; a hook-shaped folding partition is bended along the corner of the arc folding partition; the corresponding place between the bottom of the slide shell and the arc folding partition of the slide core is provided with a groove-shaped folding partition; the arc folding partition of the slide core and the groove at the bottom of the slide shell form a lower steel ball passageway; an inward bending wall is inward bended along the vertical folding partition out of the slide shell; the inward bending wall and a groove-shaped folding partition of the slide core form an upper steel balls passageway; and the upper steel balls passageway and the lower steel balls passageway are internally provided with the steel balls. The slide rail has the advantages of being capable of improving the separation-resistant force of the slide core and the slide shell, leading the slide core not to be speared from the slide when the vehicle meets with the end collision or the impact, comparatively reducing the slide resistance, and leading the slide to be smoother.

Description

A kind of slide rail that is used for seat

One, technical field

The utility model relates to a kind of slide rail, relates in particular to a kind of slide rail that is used for seat.

Two, background technology

The slide rail that is used for seat at present mainly is made of slip case, slide core and steel ball, mutual cooresponding folding wall is arranged on slip case and slide core, mutual cooresponding folding wall in slip case and slide core termination forms the steel ball passage, in the steel ball passage, be provided with rolling steel ball, steel ball contacts with face with the folding wall inside face that forms the steel ball passage and realizes sliding, sliding resistance is relatively large, and the slip smoothness is poor; The tractive force and the impulsive force that when running car, wave, jolt and give slide rail, when particularly the seatbelt attachment point places the slide rail rear side, when the automobile experience knocks into the back or clashes into, if the words of slide rail insufficient strength, be accompanied by vertical squeese pressure, the ability of resisting this separating force because of slide rail is low, can make slide core and slip case divide defection that slide core is separated with slip case, causes the slide rail disabler and the obstruction that slides.

Three, summary of the invention

At above-mentioned shortcoming, the purpose of this utility model be to provide a kind of can improve slide core resist separating force with slip case, make slide core and slip case automobile meet with knock into the back or can not separate when clashing into, sliding resistance is relatively little and slide and be used for the slide rail of seat more smoothly.

Technology contents of the present utility model is that a kind of slide rail that is used for seat comprises slide core, slip case and steel ball; It is characterized in that in the lower end of the vertical folding partition of slide core being arc folding wall, hook-type folding wall is arranged along the turnover of arc folding wall; Roll over the wall corresponding position in the slip case bottom with the arc of slide core and be provided with channel shaped folding wall, the channel shaped folding wall of the arc folding wall of slide core and slip case bottom forms down the steel ball passage; The vertical folding partition invagination forms the inner bending wall outside slip case, and the hook-type folding wall of inner bending wall and slide core forms the steel ball passage; In upper and lower steel ball passage, be provided with steel ball.

Realize sliding to contact at the above-mentioned slide rail steel ball that is used for seat and the folding wall inside face that forms the steel ball passage, its sliding resistance reduces relatively, and it is more smooth and easy to slide.

The following steel ball passage that the channel shaped folding wall of the arc of slide core folding wall and slip case bottom forms in the utility model, wherein the steel ball passage that forms of the channel shaped folding wall of the arc of slide core folding wall and slip case bottom can make slide rail unlikely generation when bearing vertical squeese pressure and tractive force block and lost efficacy, the inside face of the channel shaped folding wall of the arc of slide core folding wall and slip case bottom is when being subjected to steel ball to the squeese pressure of its generation, squeese pressure arc folding wall produces elastic bending, forms on the steel ball in the steel ball passage thereby make hook-type folding wall have the inner bending wall that a normal force is applied to slip case and the hook-type of slide core to roll over wall; When this power acquires a certain degree, can make in the inner bending wall of slip case curved and contact with the hook-type folding wall work of slide core and to form a system and make a concerted effort, with the lateral stability of assurance slide rail; Wave during simultaneously for running car, the tractive force and the impulsive force that jolt and give slide rail, can make on the rear end of slide core and lift, front end presses down, on the slide rail under the steel ball of steel ball passage rear end and the slide rail steel ball of steel ball passage front end stressed, producing the keyed end with lockable mechanism in system is the centre of moment, front and back end steel ball spacing is the power system of torque, when the effect of this power system makes the stressed slide core elastic deformation that causes of the hook-type folding wall of slide core to a certain degree the time, the outside face of the front end face of the inner bending wall of slip case and the arc of slide core folding wall is in contact with one another, play a safe effect, even the automobile experience knocks into the back and clashes into, slide core is separated with slip case is also unlikely.

The advantage that the utility model had is:

1, steel ball and the folding wall inside face that forms the steel ball passage are realized sliding to contact in the utility model, and its sliding resistance reduces relatively, and it is more smooth and easy to slide.

2, slide core of the present utility model is resisted the separating force height with slip case, slide core can not be separated when the automobile experience knocks into the back or clashes into slip case.
