Abstract

A fast folding and upside down device for car seat is assembled on seat back with a mechanism which can lean forward and backward and seat. The utility model consists of a pair of break-away mechanisms of seat back which are respectively arranged on the seat frame and the chassis and a pair of upside-down position mechanisms of seat, wherein, the break-away mechanism of seat back consists of a drag-escape belt, a connecting frame and a fixed bolt; the upside-down position mechanism of seat has a plate-shaped upper fixed connecting rod, a plate-shaped lower fixed connecting rod, a plate-shaped first free plate and a plate-shaped second free plate, all of which are mounted on the seat frame and positioned on the proper position of the chassis. When the drag-escape belt is drawn backward, the drag-escape plate also move backward, thus, the catch plate rotates, and the groove breaks away from the latch axle. The seat back is leaned forward and folded; and when the seat is upside down, the spring is tensed. The first free plate and the second free plate change the position and mutually support; thus, the seat is upside down and positioned.

Description

Automotive seat fast folding and handstand device

Technical field

The utility model relates to a kind of automotive seat, is meant the automotive seat folding device especially.

Background technology

Existing automotive seat, it has different external form structures, still, please refer to Fig. 1, and the essential structure of front-row seats of vehicle is that the chair back 12, a seat 11, a swing mechanism 13 of a tool three-dimension effect external form is installed on the chassis 1 of automobile in conjunction with forming; Wherein, this swing mechanism 13 can make the chair back 12 lean forward or swing back, and is prior art as for how installing this swing mechanism 13, cushion frame 110 etc., not at this detailed description.Should have automotive seat now, it is folding to seat 11 that the chair back 12 is leaned forward, and in truck body, this seat still accounts for the tool plane space, can not be available for putting commodity.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automotive seat fast folding and handstand device, but it can make the automotive seat at high speed remove and folding handstand rapidly from the attitude of sitting, to vacate the plane space of railway carriage.

A kind of automotive seat fast folding of the utility model and handstand device, it is installed on the chair back and seat with swing mechanism, is made up of a pair of chair back releasing mechanism and a pair of seat handstand detent mechanism that are installed in respectively on cushion frame and the chassis; Wherein, this chair back releasing mechanism is made up of a drawing belt, a binding framework, a bolt of rear end plate, and this binding framework is installed on the cushion frame, and has a space to install the hook sheet that a sheet of drawing sheet and has groove with the supply and marketing bearing fit in it; This seat handstand detent mechanism, by a sheet of go up that stationary links sheet, a sheet of four-bar linkage of stationary links sheet, a sheet of first movable plate, a sheet of second movable plate down are installed in cushion frame and be installed in by link piece forms on the chassis, and snap clasp on first movable plate spring installing bar and upward the spring of stationary links sheet install bar.When drawing belt toward post-tensioning, drawing sheet also makes the hook sheet rotate backward, makes groove break away from the door bolt axle, it is folding to seat that the chair back is leaned forward, when seat stood upside down again, spring was drawn first movable plate and second movable plate are supported mutually and to make the seat location of standing upside down.

The utility model has following advantage: because the utility model is made up of a pair of chair back releasing mechanism that is installed in cushion frame and chassis respectively and a pair of seat handstand detent mechanism; When drawing belt when the post-tensioning, the chair back leans forward folding to seat, when seat stood upside down again, spring was drawn and is made the seat location of standing upside down; So, but attitude rapid remove and folding stand upside down of automotive seat at high speed from sitting vacateed the plane space of railway carriage.

Description of drawings

Below in conjunction with drawings and Examples the utility model is elaborated:

Fig. 1 is the planar view of the utility model seat appearance form;

Fig. 2 is the planar view of the utility model folded form;

Fig. 3 is the planar view of the utility model handstand form;

Fig. 4 is the enlarged drawing of the utility model chair back releasing mechanism;

Fig. 5 is the enlarged drawing of the utility model seat handstand detent mechanism.

The specific embodiment

For further specifying the purpose of this utility model, feature and effect, lift a preferred embodiment and conjunction with figs. now and be illustrated in down.This embodiment is not to any pro forma restriction of the utility model; So, all have be same as the relevant any modification of doing of the utility model spirit, must belong to category of the present utility model.

Please refer to Fig. 1,2,3, the utility model automotive seat fast folding and handstand device, be installed in and have on the chair back 12 swing mechanism 13, the three-dimension effect external form and the seat 11, it is made up of a pair of chair back releasing mechanism 2 that is installed in cushion frame 110 and chassis 1 respectively and a pair of seat handstand detent mechanism 3; Please refer to Fig. 1,4, wherein, this chair back releasing mechanism 2 is made up of a drawing belt 21, a binding framework 25, a bolt of rear end plate 26, establish a door bolt axle 261 on this bolt of rear end plate 26 and the chassis tapped bore 100 of screw lock appropriate location on chassis 1, this binding framework 25 is installed on the appropriate location of cushion frame 110, and having a space to install a sheet of drawing sheet 22 with supply and marketing 23 bearing fits in it and have the hook sheet 24 of groove 241, is that rotating shaft makes the hook sheet 24 rotatable door bolt axles 261 that break away from pin 23 promptly; This drawing belt 21 hook respectively is located on the chair back bail 211 and drawing sheet 22 of the chair back 12; Please refer to Fig. 2, drawing belt 21 is toward post-tensioning, and drawing sheet 22 also makes hook sheet 24 rotate backward, drives groove 241 and breaks away from door bolt axle 261, and the chair back 12 leans forward folding to seat 11.

Please refer to Fig. 3,5, this seat handstand detent mechanism 3 is installed in cushion frame 110 and is installed in by link piece 33 that institute forms on the appropriate location on chassis 1 by a sheet of stationary links sheet 31, a sheet of four-bar linkage of stationary links sheet 32, a sheet of first movable plate 34, a sheet of second movable plate 35 down gone up; This link piece 33 is by the tapped bore 101 of bolt of rear end plate 331 screw locks appropriate location on chassis 1, and stationary links sheet 32 was installed in cushion frame 110 under stationary links sheet 31 reached on this, and this time stationary links sheet 32 also links link piece 33 by connecting pin 321 and is integral; This first movable plate 34 is snug fit at link piece 33 by first removable pin 332, is snug fit at second movable plate 35 by second removable pin 341; This second movable plate 35 is snug fit at stationary links sheet 31 by last removable pin 311, and spring 351 drag hooks reach the spring installing bar 353 of stationary links sheet 31 at the installing of the spring on first movable plate 34 bar 352 again.

Please refer to Fig. 3, when seat stood upside down, spring 351 was drawn to make first movable plate 34 and second movable plate, 35 change positions support and make seat handstand location mutually.
