Abstract
The invention discloses a driver seat framework with sliding rails. A backrest framework comprises a left backrest large edge plate, a right backrest large edge plate and an integrated backrest framework bend. The integrated backrest framework bend is formed by bending the same steel pipe into a rectangular frame. One end of the steel pipe is inserted into the other end of the steel pipe in a pipe retracting manner and the two ends are welded together in a butt joint manner. Square headrest metal pipes are welded to the front portions of local flattened portions of the front portion of an upper transverse pipe section. A safety belt lock catch is arranged in the right backward position of a seat frame framework, the front end and the rear end of the left side of the seat frame framework are connected with the left sliding rail through independent supports respectively, and the front end and the rear end of the right side of the seat frame framework are connected with the right sliding rail through the same integrated support. Part of stress of the backrest framework can be rapidly transmitted to an angle regulator through the large integrated bend, part of stress of the position of the safety belt lock catch can be dispersed and transmitted to the front end of the upper sliding rail, the stress borne by the right sliding rail overall is basically even, and the safety test requirement is met easily.
Description
Technical field
The present invention relates to automotive seating art field, be specifically related to a kind of structure of driver's seat skeleton.
Background technology
As shown in Figure 4, driver's seat backrest frames forms primarily of the half of formula bend pipe 4 of large on the right side of side plate 1 large on the left of backrest, backrest side plate 2, backrest recliner core members 3 and backrest frames.On the left of backrest, the lower end of large side plate 1 is provided with backrest recliner core members 3.When backrest frames does fatigue durability test, on the left of backrest, on the right side of large side plate 1, backrest, large side plate 2 is more concentrated with backrest frames half of formula bend pipe 4 weld stress amplitude ratio, easily ruptures, thus causes test failure to pass through.
As shown in Figure 5, safety belt lock catch 7 is equipped with in position rearward in the right side of driver's seat seat frame skeleton 1.The front and back ends in the left side of seat frame skeleton is connected with left side slide rail 6 respectively by independent support 8, and the front and back ends on the right side of seat frame skeleton is also connected with right side slide rail 5 respectively by independent support 8.Left and right side slide rail 6,5 is all made up of upper slide rail and glidepath.Because safety belt lock catch 7 is equipped with in position rearward in the right side of seat frame skeleton, therefore, all stress all concentrates on unsettled section of the upper sliding rail rear end in right side, when crossing the test of seat national standard regulation (i.e. GB/14167 belt anchorage point test), this section is very easy to fracture, and test cannot be passed through.
Summary of the invention
The present invention is intended to solve chaufeur backrest frames welding stress and concentrates, and produces the problem of fracture; And the problem that on the right side of chaufeur seat frame skeleton, on slide rail, sliding rail rear end unsettled section of stress is concentrated, avoid this section to rupture, meet seat national standard regulation test requirements document.
For this reason, the technical solution adopted in the present invention is: a kind of driver's seat skeleton with slide rail, comprise backrest frames, seat frame skeleton, right side slide rail and left side slide rail, the lower end of described backrest frames is connected with the rear end of seat frame skeleton and forms cushion frame, it is characterized in that:
Described backrest frames comprises large side plate on the left of backrest, large side plate and backrest frames integral type bend pipe on the right side of backrest, on the left of described backrest, the lower end of large side plate is provided with backrest recliner core members, backrest frames integral type bend pipe is bent by same steel pipe to form, and by upper lateral tube section, bottom rail pipeline section, the rectangle frame that left standpipe section and right standpipe section surround, one termination of steel pipe adopts draw mode to insert in another termination of steel pipe, and to ground connection weld together, described left standpipe section is welded on the inwall of large side plate on the left of backrest, right standpipe section is welded on the inwall of large side plate on the right side of backrest, the anterior left and right of described upper lateral tube section is arranged at intervals with flattening portion, two local, the front in flattening portion, each local is welded with a metal headrest square tube,
Safety belt lock catch is equipped with in position rearward in the right side of described seat frame skeleton, the front and back ends in the left side of seat frame skeleton is connected with left side slide rail respectively by independent support, the front and back ends on the right side of described seat frame skeleton is connected with right side slide rail by same integral support, the upper slide rail of described integral support and right side slide rail is isometric, integral support is stamping forming sheet metal component, this sheet metal component comprises horizontal plate, in-flanges and flanging, two local of described flanging upwards extend to form installation journal stirrup, install journal stirrup for two and are connected with the front and back ends on the right side of seat frame skeleton respectively.
Preferred as such scheme, the rear end described safety belt lock catch, integral support are positioned on the right side of the installation journal stirrup of rear side, seat frame skeleton is fastened by bolts together, described integral support is also provided with anti-rotation fixture block to rotate for preventing safety belt lock catch, the installation journal stirrup root punching described integral support being positioned at rear side has reinforced rib.
Beneficial effect of the present invention:
(1) backrest frames big syphon is designed to integral type bend pipe, and bend pipe two ends joint interts in the other end in the mode of a draw, is then connected with welding manner.Backrest frames is in fatigue durability test process, and part stress is delivered to rapidly in recliner by overall big syphon, only has a very little part to act on the large side plate of backrest left and right side, thus is very easy to by backrest frames fatigue durability test.
(2) cancel two independent supports that on the slide rail of right side, slide rail is corresponding, increase by one piece of integral support and be connected with chaufeur seat frame skeleton.When crossing the test of seat national standard regulation (i.e. GB/14167 belt anchorage point test), the stress of part can disperse the front end being delivered to slide rail, overall sideslip rail is met with stresses substantially even, easily meets safety test requirement.
