The specific embodiment

Embodiment 1,

The mechanical collision safety of automotive seat is stepped back fender guard, comprises collision touch part, hammerlock 3, movable arm 4, slide bar 5, external chute 7, push arm 8, external spring 9, built-in spring 10; Wherein: an end of collision touch part and hammerlock 3 flexibly connects, the other end of hammerlock 3 is connected with fixed support 12 springs by built-in spring 10, the other end of hammerlock 3 is connected with an end of movable arm 4, the keyhole of the other end of movable arm 4 and slide bar 5 flexibly connects, external chute 7 is fixed on fixed support 12 upper ends, slide bar 5 and external chute 7 bearing fits, being connected on the slide bar 5 of an end activity of external spring 9, the other end of external spring 9 is fixed on the external chute 7.

In actual use, the setting of built-in spring 10 is to fasten in order to allow the other end of movable arm 4 be connected with the keyhole of slide bar 5 smoothly.When the other end of movable arm 4 is connected with the keyhole of slide bar 5 when fastening smoothly, external spring 9 is strained.

Fixed support 12 is the inner bottom parts that are fixed on operator's compartment, is connected with automotive seat on the slide bar 5, and a kind of common connection mode is that slide bar 5 is provided with the mounting hole that automotive seat are installed, and automotive seat are installed on the slide bar 5 by bolt.

Affect hammerlock 3 when the collision touch part strong external force of impression, hammerlock 3 affects movable arm 4 again, movable arm 4 is deviate from from the keyhole of slide bar 5, and the external spring of tension loses restriction, sudden contraction, because external chute 7 is to be fixed on the fixed support 12, and fixed support 12 is the inner bottom parts that are fixed on operator's compartment, and this moment, slide bar 5 slided in external chute 7, and slide bar 5 moves to the rear of truck body, the driving automobile seat is stepped back rapidly, avoids or alleviates the injury of strong external force to the people.

Embodiment 2,

The mechanical collision safety of automotive seat is stepped back fender guard, and wherein: the collision touch part is the attaching parts that push arm 8, movable handle 2 are formed, and an end of push arm 8 is connected with movable handle 2, and movable handle 2 flexibly connects with an end of hammerlock 3.

Push pedal 1 is installed between bearing circle and the push arm 8 under the situation at ordinary times, but push arm 8 is not touched in push pedal 1.If meet the traffic accident that headstock is clashed into, the push pedal 1 of car body under the violent twisting situation of predecessor and the other end collision of push arm 8, push arm 8 can move to the rear of truck body by drive activity handles 2, and movable handle 2 promotes hammerlocks 3, gives strong external force and promotes hammerlock 3.Hammerlock 3 moves to tailstock direction.All the other are with embodiment 1.

Embodiment 3,

The mechanical collision safety of automotive seat is stepped back fender guard; wherein: the collision touch part is the attaching parts that steering wheel bottom seat support 11, draught line 6 are formed; draught line 6 one ends are connected with steering wheel bottom seat support 11, and an end of draught line 6 other ends and hammerlock 3 flexibly connects.

Draught line 6 is not worked under the situation at ordinary times, if meet the traffic accident that headstock is clashed into, car body is under the violent twisting situation of predecessor, and steering wheel bottom seat support 11 ruptures or topples over backward and all can draw tension draught line 6, draught line 6 pulling hammerlocks 3 are given strong external force pulling.Hammerlock 3 moves to the headstock direction.All the other are with embodiment 1.

No matter be that strong external force promotes or the pulling of strong external force in embodiment 2 or 3, the changing of the relative positions of hammerlock 3 will affect movable arm 4 again, makes movable arm 4 deviate from from the keyhole of slide bar 5.
