Abstract
The invention discloses an assembling structure of an automobile seat bent spring. The assembling structure comprises front and back transverse beams of a seat framework, and a plurality of bent springs arranged between the front and back transverse beams of the seat framework, wherein the front ends of the adjacent two sections of the bent springs are bent downwards in an arc shape and are transversely connected to form a hook part; the front ends of the bent springs are hooked on the outer periphery of the front transverse beam of the seat framework through hooking parts; connection holes which correspond to all sections of the bent springs one by one are formed in the back transverse beam of the seat framework; the back ends of the bent springs are bent to be an L shape and are inserted into the connection holes in the back transverse beam of the seat framework. According to the assembling structure, an assembling process can be simplified, the weight of a seat is lightened and the production cost is reduced.
Description
Technical field
The present invention relates to automotive seat parts, be specifically related to the mounting structure of the bent spring of a kind of automotive seat.
Background technology
Along with the large-scale batch production of automobile product, require also more and more higher to the assembly process process of auto parts and components, require that parts assembly technology is simple, be easy to realize mass production, the labour intensity of operator is little, is conducive to the beat improving manufacturing line, ensures the quality of product.
See Fig. 2, in the bent spring mounting structure of existing automotive seat, many independently snakelike bent spring be assemblied between the forward and backward crossbeam 2,3 of cushion frame side by side, the two ends of the bent spring 1 of described every root are hung in the hook support 4 that is welded on forward and backward crossbeam, for avoiding bent spring and hook support to produce abnormal sound, be arranged with rubber coating 103 at the two ends of bent spring.
But this assembling mode exists some shortcomings, one is that the bent spring of every root all needs corresponding two hook support, and for whole seat, the hook support of One's name is legion increases the weight of seat undoubtedly, and brings a large amount of welding sequences.Two is that the up, down, left, right, before and after direction at described bent spring two ends realizes spacing by hook support, in the actual use procedure of seat, bent spring is subject to the External Force Acting in above-mentioned 6 directions, bent spring produces relative motion with hook support together with the rubber coating of its front and back ends, the rubber coating of bent spring front and back ends becomes linear contact lay with hook support, breaking very easily under external force in linear contact lay position, causes the hook support effect that is direct and metal material of bent spring to produce and rub or clash into abnormal sound.
Summary of the invention
The object of the present invention is to provide the mounting structure of the bent spring of a kind of automotive seat, can assembly technology be simplified, alleviate seat-weight, reduce productive costs.
The mounting structure of the bent spring of automotive seat of the present invention, the some bent spring comprising the forward and backward crossbeam of cushion frame and be located between the forward and backward crossbeam of cushion frame, the downward arc bending in front end of two sections of adjacent bent springs is also laterally connected, form a hook portion, the front end of described bent spring is hooked on described cushion frame front cross rail outer peripheral face by hook portion from top, described cushion frame after cross member offers the bent spring connecting bore one to one with every section, the bending of described bent spring rear end in L-type, and is inserted and is hung on the connecting bore of described cushion frame after cross member.
The hook portion Surface coating rubber sleeve of described bent spring, is also coated with rubber coating in bent spring rear end and surface, connecting bore contact site.
In mounting structure of the present invention, the two ends of bent spring are directly connected with cushion frame crossbeam, eliminate the hook support in existing mounting structure, simplify assembly technology, eliminate the weight of hook support.In addition, in this mounting structure, bent spring front end coordinates with arc surface all the time with cushion frame front cross rail, and rubber coating uniform force, not easily breaks.The rear end of bent spring realizes the spacing of all directions by connecting bore, and this mounting structure is reliable, in use can not produce abnormal sound.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the mounting structure schematic diagram of existing bent spring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated, and following examples only for explaining the present invention, do not form limiting the scope of the present invention.
The mounting structure of the bent spring of automotive seat as shown in Figure 1, comprise the forward and backward crossbeam of cushion frame and be located at the snakelike bent spring 1 of between the forward and backward crossbeam of cushion frame some sections, downward for the front end of adjacent two sections of bent springs arc bending is also laterally connected, form a hook portion 101, the front end of described bent spring is hooked on described cushion frame front cross rail 2 outer peripheral face from top by hook portion 101, and the mode of being moulded by plastic or leaching on hook portion 101 surface of described bent spring is coated with rubber coating 103.
Described cushion frame after cross member 3 offers the bent spring connecting bore 301 one to one with every section, described bent spring rear end 102 bends in L-type, and insert and hang on the connecting bore 301 of described cushion frame after cross member, at bent spring rear end 102 and connecting bore contact site Surface coating rubber sleeve 103.
When assembly manipulation, first described bent spring rear end is inserted in the connecting bore hanging over cushion frame after cross member, then pull forward bent spring, the hook portion of bent spring front end is hung on cushion frame front cross rail, just complete the assembling of bent spring with cushion frame, now bent spring is tensioning state.
Claims (2)
1. the mounting structure of the bent spring of automotive seat, before comprising cushion frame, after cross member (2, 3) and before being located at cushion frame, some bent spring (1) between after cross member, it is characterized in that: the downward arc bending in front end of two sections of adjacent bent springs is also laterally connected, form a hook portion (101), the front end of described bent spring is hooked on described cushion frame front cross rail outer peripheral face by hook portion from top, described cushion frame after cross member offers the bent spring connecting bore (301) one to one with every section, described bent spring rear end (102) bending is in L-type, and insert hang on the connecting bore of described cushion frame after cross member.
2. the mounting structure of the bent spring of automotive seat according to claim 1, is characterized in that: hook portion (101) the Surface coating rubber sleeve (103) of described bent spring, is also coated with rubber coating (103) in bent spring rear end and surface, connecting bore contact site.
