Abstract

The utility model provides a safety driving seat capable of timely backward sliding, comprising a track type base seat which is connected with a vehicle box and a sliding seat frame which is arranged at the lower part of the seat and is matched with the track type base seat. The utility model is characterized in that a positioning mechanism causes the seat to move backward automatically and moves backward automatically by a positioning mode when brute force braking is carried out in the safety driving seat. When an accident occurs, the seat can timely backward so that the safety of a driver is ensured.

Description

The safe driver seat that moves after can be in time

The utility model provides a kind of safe driver seat, particularly be a kind of safe driver seat that moves after can be in time.

The existing seat that is used for operator's compartment comprises with compartment bonded assembly rail mounted pedestal, is loaded on the sliding seat frame that cooperates with the rail mounted pedestal of seat bottom.Such seat is locked after the position mixes up, must be by the conscious position that could change seat of adjusting of chaufeur.When being about to have an accident, chaufeur has little time to adjust the position of seat and makes seat still keep original position, and fatal accident very easily takes place.

In view of above reason, the purpose of this utility model be can make when a kind of having an accident is provided guaranteed driver safety that seat moves in time can be in time after the safe driver seat that moves.

The utility model is the improvement on the basis of existing driver seat, it is characterized in that having move after making seat automatically when carrying out heavy braking and can locate automatic after move detent mechanism (referring to Fig. 1～Fig. 4).

Above-mentioned move after automatically to have in the detent mechanism be positioned at pedestal one side and be fixed on the locations that contains several latches on the compartment, be hinged on the handle on the seat support, can stretch into the block tongue in the latch groove, plate is adjusted in the extension spring that floats in the sliding seat frame, one end of adjustable bolt passes the front end of pedestal and is contained on the adjustment plate, one end of several extension springs is contained in the rear end of sliding seat frame respectively and the other end is contained in respectively and adjusts on the plate (referring to Fig. 1, Fig. 2), the elasticity of scalable extension spring, the extension spring elasticity during with the chaufeur normal running seat stablize motionlessly, move behind the seat when chaufeur touches on the brake resolutely to suitable.

Spring (referring to Fig. 1) is housed between above-mentioned handle and block tongue.

Above-mentioned moving after automatically has the chute of being located on the automotive frame in the detent mechanism, place the trip iron in the chute, pulley (19,20) is arranged on automotive frame, steel rope one end is connected with the sliding seat frame and the other end is walked around pulley (20,19) and be connected the trip iron on (referring to Fig. 3).

The above-mentioned chute place that is located on the automotive frame has and crossbeam bonded assembly support, and support top is positioned at trip iron and places on the runner rear end position stage clip is arranged, and has under the stage clip and under normal circumstances will swim the unrooted iron (referring to Fig. 4) that iron is pushed down.

During work, earlier with handle and leg strength, press the chaufeur stature and adjust the seat front and back position, the handle of letting go is stuck in the latch groove block tongue, adjusts extension spring intensity, makes it when the normal brake application step on the gas, seat is stablized motionless, and when heavy braking, both legs were firmly pedaled forward, seat can move backward, was safe work state.When running into emergency situation footbrake heavy braking, seat in time moves backward, has avoided the generation of accident.Recover cruising, mention handle, seat can reset.When running into emergency situation and have little time brake and take place to collide because strenuous vibration; trip iron leaves unrooted iron and washes away forward (during cruising; trip iron is being swum the groove rear end by stage clip and unrooted ferropexy; trip iron front end and chute anteromedial surface are gapped); steel rope drives seat and moves backward, promptly reaches the purpose of protection driver safety.

The utility model can make driver seat move in time when having an accident, and has guaranteed the safety of chaufeur.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is that slide rail pedestal and sliding seat frame, extension spring mutual alignment concern scheme drawing.

Fig. 3 is sliding seat frame, trip iron annexation scheme drawing.

Fig. 4 concerns scheme drawing for trip iron, stage clip, the mutual position of unrooted iron phase.

Referring to Fig. 1, Fig. 2, rail mounted pedestal 1 is fixed on the cabin floor, the sliding seat frame 3 and rail mounted pedestal 1 bearing fit of seat 2 bottoms.Automatically moving the locations that contains several latches 56 in the detent mechanism 4 after is positioned at the left side of pedestal 1 and is fixed on the cabin floor.Handle 7, can stretch into the latch groove in the locations 6 and the block tongue 8 that cooperates with the latch groove is hinged on the seat support.8 of handle 7 and block tongues have spring 9.The jump ring 10 that handle 7 is blocked is arranged on the seat support.Setting of spring plate 11 floats in the sliding seat frame, and adjustable bolt 12 passes the front end of pedestal and is connected on the setting of spring plate 11.On setting of spring plate and sliding seat frame opposite position, four

links

13,14 are housed respectively.The two ends of four extension springs 15 are stretched into respectively and are connected in the corresponding link on setting of spring plate and the sliding seat frame.

Referring to Fig. 3, Fig. 4, on automotive frame 16, be provided with chute 17, the trip iron 18 of heavy 80kg is loaded in the chute.When trip iron 18 placed runner rear end, the distance of trip iron front end face and chute anteromedial surface was about 15 centimetres.Be provided with

pulley

19,20 on crossbeam, steel rope 21 1 ends are connected on the sliding seat frame and the other end is walked around

pulley

20,19 and is connected with trip iron.Being positioned at the chute place on crossbeam has support 22, and stage clip 23 is loaded on the top of support 22, and when cruising, trip iron places runner rear end, and unrooted square iron 24 is arranged on it, and an end of stage clip 23 is pressed on the unrooted square iron and will swims ferropexy in chute.
