Abstract
The invention discloses a waist and back pneumatic supporting device which is arranged between a supporting spring frame of a seat backrest and a backrest foaming cushion. The waist and back pneumatic supporting device comprises a forward flexible shielding plate, a top supporting airbag and a supporting back plate; the forward flexible shielding plate is arranged between the top supporting airbag and the backrest foaming cushion; the supporting back plate is arranged between the top supporting airbag and the supporting spring frame; the top supporting airbag is arranged between the supporting back plate and the forward flexible shielding plate. According to the waist and back pneumatic supporting device, a phenomenon that an original inflatable airbag is easy to sink into the back part of the backrest foaming cushion capable of being elastically deformed is changed. The previous convex inflatable airbag is ejected against the forward flexible shielding plate and is ejected against the back part of the backrest foaming cushion by the forward flexible shielding plate, so that a phenomenon that a seat surface of the seat backrest is not smooth enough is avoided. Compared with a pneumatic back supporting adjusting device of the top supporting airbag of a multi-grade airbag of a larger seat surface supporting route, the seat surface top supporting effect has the obvious smooth change. The invention further discloses an automobile seat.
Description
Technical field
The present invention relates to automotive seating art field, more particularly, relate to a kind of the small of the back Pneumatic support device and automotive seat.
Background technology
Along with the development in science and technology in vehicular communication field, people are more and more higher for the requirement of vehicle riding comfort.A kind of the small of the back support technology of seat also arises at the historic moment, and is progressively applied to Passenger motor vehicle field, middle and high end.
In the past, this type of Seat lumbar support technology used mechanical support and pneumatic support two kinds of Form of Techniques usually.Pneumatic support be adopt miniature air pump as propulsion source by air through relevant control valve body, be blown into be placed in back of seat foam pad rear portion shore in pneumatophore, by the inflation/deflation of pneumatophore, realize the local projection or calm of backrest seat seat, and then realize the small of the back supporting role to human body.
A simple application of air bag product shored by this type of seat, shores air bag exactly by one, is arranged on the plastic support backboard between back rest supports spring support and backrest foam pad.When shoring air bag by air-pump inflating, shoring air bag and be inflated and produce protruding stroke, and then by backrest foam pad jack-up forward, and then make side in face of chair that projection occur.
But protruding shores air bag while the jack-up of seat front, shore air bag and can push up and be pressed on backrest foam pad, and be easy to the rear portion being absorbed in relatively soft backrest foam pad to a certain extent.When the mat body thickness of backrest foam pad is partially thin, that it causes as a result, after each shores airbag aeration, that back of seat seat is occurred is smooth-going not for the air bag top pressure surface of shoring be inflated, occupant's waist has lofty sense phenomenon, easily causes being discontented with of seat user.This lofty irregularity phenomenon is especially obvious the pneumatic back-supported control apparatus shoring air bag supporting the multi-stage gasbag of stroke for adopting larger seat.
Therefore, how to avoid the seat of back of seat to occur problem smooth-going not, become the technical matters that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
