Detailed description of the invention
Core of the present utility model is to provide a kind of the small of the back Pneumatic support device and automotive seat, to promote the protruding stroke shoring air bag.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 3, the structural representation of the small of the back Pneumatic support device that Fig. 1 provides for the utility model embodiment; The construction profile schematic diagram of the automotive seat that Fig. 2 provides for the utility model embodiment; The construction profile schematic diagram of the automotive seat that Fig. 3 provides for another embodiment of the utility model.
The small of the back Pneumatic support device that the utility model embodiment provides, for being arranged between the support spring support 04 of backrest 01 and foam pad 06.The small of the back Pneumatic support device 10 comprises supporting back board 11 and shores air bag 20.In addition, the small of the back Pneumatic support device 10 also should have solenoid electric valve 12, air pump 13, gas-guide pipeline 14 and external control circuit (not shown), solenoid electric valve 12, air pump 13, gas-guide pipeline 14 and external control circuit do not relate to improvement of the present utility model, will not describe in detail herein at this.
Shore between air bag 20 and described support spring support 04 described in described supporting back board 11 is arranged at; Described first order utricule 21 and the second stage utricule 22 shored air bag 20 and at least comprise arranged stacked.
When the small of the back Pneumatic support device that the utility model provides is opened and is shored airbag aeration work, the utricules at different levels shoring air bag 20 are mutual layered relationship between support spring support 04 and foam pad 06, namely under utricule inflated condition at different levels, form mutually stacked form, the charging stroke shoring air bag 20 is inflatable material sums at different levels.Now, foam pad 06 and seat 03 are by jack-up state.When the utricules at different levels shoring air bag 20 lose heart, mutually stacked utricules at different levels be deflated and be tending towards contracting flat, foam pad 06 and seat 03 gradually recover to calm down state.When shoring air bag 20 in the deflated condition, utricule at different levels can act on the pressure of supporting back board 11 and support on spring support 04.
The protruding stroke of inflation that original single stage type is shored air bag by the utility model becomes the protruding stroke sum of multiple air bag, and the waist traveling comfort achieving larger seat stroke supports and regulates.The utility model can solve an application engineering difficult problem for this series products preferably, and the waist traveling comfort that have effectively achieved larger seat stroke supports and regulates.
Further, shore air bag 20 described in and also can comprise the third stage utricule 23 with described second stage utricule 22 arranged stacked.Described first order utricule 21, second stage utricule 22 are all connected with described third stage utricule 23, and are communicated with the gas-guide pipeline 14 of same intake and exhaust.In addition, described first order utricule 21, second stage utricule 22 and described third stage utricule 23 also can be utricule independent of each other, and the gas-guide pipeline 14 of corresponding with it the respectively intake and exhaust of each utricule is communicated with, in the case, utricule at different levels, except can inflate simultaneously, also can connect solenoid electric valve 12 respectively and inflate separately.
In the utility model one specific embodiment, described supporting back board 11 is elasticity backboard.Supporting back board 11 adopts the elasticity backboard with the elastically deformable of some strength to be favourable.Adopt the elasticity backboard with the elastically deformable of some strength can while effectively reducing supporting back board 11 impression deformation, there is the plate that certain elastically deformable feature can reduce backrest 01 and firmly feel, improve the comfort level that human body is taken.
In the utility model one specific embodiment, the area near the described first order utricule 21 of described support spring support 04 is greater than the area of described second stage utricule 22.Between foam pad 06 and the pneumatophores at different levels shoring air bag 20 supported between spring support 04 have employed shore air bag area not geometric ratio be favourable.The first order utricule 21 of larger area be placed in close on support spring support 04 supporting back board 11 on, foam pad 06 side is closed in the top that second stage utricule 22 is placed in first order utricule 21.Under utricule inflated condition at different levels, be pressed in compared with second stage utricule 22 top of small size and foam pad 06 make it to obtain larger pressure and to seat 03 side jack-up; And the first order utricule 21 of larger area carries the pressure of second stage utricule 22, and form relatively little pressure action in supporting back board 11, the formation towards supporting spring support 04 is minimized.Thus, when identical utricule charge air at different levels, the backrest 01 of automotive seat 00 can be made to convex to form larger, waist holder effect is more obvious.
Further, described supporting back board 11 is provided with tissue layer, nonwoven fabrics bed course, spongy layer or flexible glue-line towards the side of described support spring support 04, can avoid the different sound of friction that utricule inflated condition lower support backboard 11 at different levels causes support spring support 04.
Preferably, described supporting back board 11 is fixed on described support spring support 04 or foam pad 06 by fastener 15.It is inner that the solenoid electric valve 12 of described the small of the back Pneumatic support device and/or air pump 13 are positioned over backrest 01, or below the cushion 02 being positioned over seat.
The arrangement that the small of the back Pneumatic support device 10 is placed in foam pad 06 and supports between spring support 04, the thick sponge feature of foam pad 06 can be made full use of, avoid and shore air bag 20 and be placed on the foreign body sensation being easy between seat 03 and foam pad 06 produce, and reduce the with the passing of time wearing and tearing of utricule to seat 03 inside.
The invention also discloses a kind of automotive seat 00, comprise cushion and backrest 01, be provided with the small of the back Pneumatic support device 10 in described backrest 01, wherein, described the small of the back Pneumatic support device 10 is as above the small of the back Pneumatic support device 10 disclosed in embodiment.Owing to having above-mentioned the small of the back Pneumatic support device, therefore have all technique effects of above-mentioned the small of the back Pneumatic support device concurrently, do not repeat them here herein.
In this specification sheets, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
