Abstract

A fast dismounting device for car seat is assembled on seat with a seat frame. The main technical proposal is that a pair of rear lugs with lower camber concaved face and a pair of front lugs with front camber concaved face are arranged downwardly on the seat frame; the lower camber concaved face is gradually widened along the downward direction and matched with the latch axle of the position plate of the rear lug which is arranged on the chassis of the carriage; and the front camber concaved face is gradually widened along the forward direction and matched with the latch axle of the position plate of front lug which is assembled on the chassis of carriage. The rear lug is provided with a handle which has a pull rod and a positioning catch plate which has a loop hook; the loop hook is pressed on the latch axle of the position plate of rear lug from the top. When the handle is dragged upwardly, the loop hook of the position catch plate breaks away from the latch axle, then the seat can be rapidly dismantled and moved out of the vehicle.

Description

The automotive seat device for quickly disassembling

Technical field

The utility model relates to a kind of automotive seat, particularly automotive seat stripping assembly.

Background technology

Existing automobile seat, though have different external form structures, it is folding that it only can make the chair back lean forward, in truck body, this seat still accounts for the tool plane space, can not be available and use for article.

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 quick release, and seat is moved out outside the railway carriage, to vacate the automotive seat stripping assembly of railway carriage plane space.

The utility model automotive seat device for quickly disassembling is installed on the seat with seat frame, and this seat frame is to having a pair of the have rear foot of following arc concave surface, a pair of forward foot in a step with frontal arc concave surface; This time arc concave surface is to become big cancave cambered surface gradually along downward direction, in alignment with the door bolt axle that is installed in rear foot locating plate on the railway carriage chassis, this frontal arc concave surface is that the edge is forwards to becoming big cancave cambered surface gradually, in alignment with the door bolt axle that is installed in forward foot in a step locating plate on the railway carriage chassis, install the location hook sheet that a handle, with poke rod has bail again on this rear foot, make this bail by the door bolt axle that withstands this rear foot locating plate down, fasten axle with a bolt or latch when handle upwards draws and make the bail of location hook sheet to leave.

The utlity model has following advantage: since the utility model at seat frame to having a pair of the have rear foot of following arc concave surface, a pair of forward foot in a step with frontal arc concave surface, and on this rear foot, be equiped with handle with poke rod and location hook sheet with bail, make this bail by the door bolt axle that withstands this rear foot locating plate down, therefore, when handle upwards draws and when making the bail of location hook sheet leave the door bolt axle, can make the fast quick-detach of automotive seat, and seat moved out outside the railway carriage, to vacate the railway carriage plane space, use for article.

Description of drawings

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

Fig. 1 is the planar view that the utility model contains seat;

Fig. 2 is the planar view that the utility model is installed in rear foot locating plate;
