CN202499037U - Curved-spring buffering mesh of automobile seat cushion - Google Patents

Abstract

The utility model discloses a curved-spring buffering mesh of an automobile seat cushion. The curved-spring buffering mesh comprises a mesh consisting of curved springs (1), and is characterized in that plastic tubes (2) are sleeved on hook portions of two ends of the curved springs (1), the middles of the curved springs (1) are connected through a plastic connecting piece (3). According to the above technical scheme, plastic tubes are sleeved at two ends of the curved springs, friction between the curved springs and metal fixing parts of a frame of the cushion can be reduced, abnormal noise is reduced, the middles of the curved springs are connected through the plastic connecting piece, and relative moving of the curved springs can be avoided, so that stress on the curved springs can be spread well.

Description

The bent spring buffering of automotive seat cushion grid

Technical field

The utility model relates to a kind of parts of automotive seat, particularly the bent spring buffering of a kind of cushion of automotive seat grid.

Background technology

The skeleton of automotive seat cushion has the complete bent spring formula skeleton (as shown in Figure 1) of employing, full seat benzvalene form seat cushion framework and half half benzvalene form skeleton of bent spring (as shown in Figure 2) at present; Adopt bent spring buffering grid can when approaching the seat cushion foam, obtain identical traveling comfort; In some body layout,, can also become space-saving method for arranging in order to obtain bigger vehicle body space.On complete bent spring formula skeleton and half half benzvalene form skeleton of bent spring, all can be connected the grid of being made up of bent spring, the two ends with an independent bent spring are fixed on the connecting element at skeleton two ends in fact exactly.Such cushion; The extruding that people can not stop when taking unavoidably and leave cushion, at this moment, the hook at bent spring two ends will rub with the metal piece of skeleton mutually; Produce abnormal sound; And bent spring grid is actual to be many separate bent springs, occurs the situation of single bent spring sway easily, reduces the traveling comfort of seat.

The utility model content

The utility model technical matters to be solved is to provide a kind of can reduce the cushion abnormal sound, avoids bent spring sway, improves the bent spring buffering of the automotive seat cushion grid of cushion traveling comfort.

To achieve these goals; The technical scheme of the utility model is following: the bent spring buffering of a kind of automotive seat cushion grid; Comprise the grid of forming by bent spring (1); The hook portion at the two ends of said bent spring (1) is with plastic pipe (2) outward, and the middle part of all bent springs (1) connects through plastics contiguous block (3).

Adopt technique scheme,, can reduce the friction between bent spring and the cushion skeleton metal fixing the equal overcoat plastic pipe in the two ends of bent spring; Reduce abnormal sound; Connect with the plastics contiguous block at the middle part of bent spring, can avoid bent spring to relatively move, make that bent spring is stressed better to be distributed.

In technique scheme: an end of said bent spring (1) is " semicircle " shape hook, and the other end is " L " shape hook, said " semicircle " shape hook and the outer plastic pipe (2) that all is set with of " L " shape hook.Suitable half half the benzvalene form skeleton of bent spring of the bent spring of this form, semicircle hook are better to fix for better and cushion rear cross-tube, and " L " shape hook then is to fix with half basin of skeleton front end.

In technique scheme: be provided with salient point (2a) on the plastic pipe (2) outside said " L " shape hook.Can prevent bent spring and half basin slide relative.

In technique scheme: the two ends of said bent spring (1) are " L " shape hook.Bent spring like this is fit to complete bent spring formula skeleton to be used.

In technique scheme, said plastics contiguous block (3) is provided with through hole (3a).In punching on the plastics contiguous block is that (such as heating, SBR, motorized adjustment function etc.) can be used for that wire harness is fixing to be used when increasing configuration at seat.

Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, low cost of manufacture, can reduce seat backrest cushion back of the body abnormal sound, improves traveling comfort.

Description of drawings

Fig. 1 is complete bent spring formula cushion skeleton;

Fig. 2 is half benzvalene form cushion skeleton of half bent spring;

Fig. 3 is the structural representation of the utility model embodiment 1.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Embodiment 1, and shown in Fig. 2-3, the parts such as grid, plastic pipe 2 and plastics contiguous block 3 that the bent spring buffering of the automotive seat cushion of the utility model grid is made up of bent spring 1 are formed; Said cushion skeleton adopts half half benzvalene form skeleton of bent spring; The rear portion of cushion skeleton is provided with transverse tube, and the front portion is provided with half basin, on half basin, is provided with bent spring connecting element; This is a prior art, does not do at this and gives unnecessary details.The hook portion at the two ends of said bent spring 1 is with plastic pipe 2 outward, and the middle part of all bent springs 1 connects through plastics contiguous block 3.Said plastics contiguous block 3 is provided with through hole 3a.One end of said bent spring 1 is semicircle hook, and the other end is " L " shape hook, said semicircle hook and the outer plastic pipe 2 that all is set with of " L " shape hook.The outer plastic pipe 2 of said " L " shape hook is provided with salient point 2a.Said semicircle hook is fixed on the rear crossbar, and said " L " shape hook then is fixed on the bent spring connecting element on half basin.

The utility model is not limited to the specific embodiment 1; The two ends of said bent spring 1 are the bent spring of " L " shape this kind of hook and are fit to complete bent spring formula cushion skeleton; Of Fig. 1; Plastic pipe 2 is established at two ends at the bent spring 1 of Fig. 1, and the middle part of the bent spring 1 among Fig. 1 coupled together through plastics contiguous block 3 does not equally draw among the figure, but those skilled in the art just can draw its structure according to Fig. 3.

Claims (5)

1. the bent spring buffering of an automotive seat cushion grid comprises the grid of being made up of bent spring (1), and it is characterized in that: the hook portion at the two ends of said bent spring (1) is with plastic pipe (2) outward, and the middle part of all bent springs (1) connects through plastics contiguous block (3).

2. according to the bent spring buffering of the said automotive seat cushion of claim 1 grid; It is characterized in that: an end of said bent spring (1) is " semicircle " shape hook; The other end is " L " shape hook, said " semicircle " shape hook and the outer plastic pipe (2) that all is set with of " L " shape hook.
