Description

The motor vehicle seat back hook structure

Technical field

The utility model relates to a kind of hook structure, espespecially a kind of motor vehicle seat back hook structure.

Background technology

For automotive seat, the rules GB15083-2006 of China's enforcement in February, 2007 has increased the special stipulation that prevent that in automobile collision procedure, the mobile luggage in baggage container injures the member.This regulation consists of the situation of a boot compartment part mainly for the back seat backrest of most manned vehicles and headrest thereof, thereby purpose is to prevent when seat is subject to mobile luggage and impacts in automobile collision procedure to cause injury to the member with the inefficacy of vehicle body point of connection.

See also Fig. 1, existing motor vehicle seat back hook relies on friction force that hook 2 is remained in vehicle body mounting hole 3 mostly, when the luggage impulsive force excessive, and when the body platform in the vertical direction is subjected to displacement, very big unhook risk is arranged, thereby back of seat 4 is dumped forward, cause the member to injure.

See also Fig. 2, existing rear steam discharge vehicle seats, much main engine plants when doing the high-end vehicles back seat, can additionally increase Crashworthy plate, are used for preventing that seat from causing the injury to the member when automobile collision procedure is subject to mobile luggage impact.

For the ease of installing, Crashworthy plate is fixed by a

pre-determined bit pin

2 and 3 bolt combination usually, and some main engine plants also require to install from the front, do not allow to play forward bolt from baggage container.The general friction force that relies on of Crashworthy plate pre-determined bit pin 2 remains in vehicle body mounting hole 3, when luggage impacts, if Crashworthy plate is partially soft, causes cross travel larger, and pre-determined bit pin 2 is just easily deviate from from the hole, thereby may damage the occupant.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and provide a kind of motor vehicle seat back hook structure, realized that a kind of backrest frames of can not only arranging is by the baggage container Collision test after making on the automobile direct of travel, and can be at body platform generation vertical direction during to top offset, backrest hook does not still break away from the motor vehicle seat back hook structure of vehicle body mounting hole, has high safety, the characteristics that easy for installation, cost is low.

The technical scheme that realizes above-mentioned purpose is:

A kind of motor vehicle seat back hook structure of the present utility model comprises support and hook, and described support is fixed on vehicle body; Described support forms the hook groove; Described hook comprises a body of rod and is formed at the flange of described body of rod first end; The body of rod of described hook is arranged in described hook groove and is located on described support by described hook flange.

Further improvement of the utility model is, described support and motor vehicle seat back be arranged in parallel; The second end of the described body of rod is fixed on described motor vehicle seat back.

Further improvement of the utility model is, described hook groove comprises an elongated slot section and be formed at respectively a macropore and an aperture at described elongated slot section two ends, and described elongated slot section width coordinates with the described body of rod, and the diameter of described macropore coordinates with described flange; The described body of rod is inserted in described aperture.

Further improvement of the utility model is, also comprises a Crashworthy plate, and the surface of described support is parallel with the automobile direct of travel; The second end of the described body of rod is fixed on a connection bracket of described Crashworthy plate.

Further improvement of the utility model is, described hook groove is the open slot that is formed at described stent side portion; Described hook groove comprises the elongated slot section of a first end opening and is formed at the round hole part of described elongated slot section the second end; The width of described elongated slot section matches with the described body of rod, and the diameter of described round hole part is greater than the diameter of the width of described elongated slot section and the described round hole part diameter less than described flange.

Further improvement of the utility model is, the cross section ovalize of the described body of rod, and the width of described elongated slot section matches with the minor axis length in described body of rod cross section, and the diameter of described round hole part matches with the long axis length in described body of rod cross section.

The utility model has been owing to having adopted above technical scheme, makes it have following beneficial effect to be:

When the flange of rod end has prevented that automobile is subject to greater impact, hook is deviate from the hook groove; The support that wherein be arranged in parallel with motor vehicle seat back and the employing of corresponding hook guaranteed that at body platform generation vertical direction the backrest hook does not still break away from the hook groove during to top offset, avoided may to the occupant damage may; In addition in the employing of the parallel support of automobile direct of travel and corresponding hook, because Crashworthy plate deformation causes the larger cross travel of hook cadre, prevent from that the body of rod from deviating from from the hook groove passenger is damaged when having prevented that automobile is subject to greater impact from the rear portion.Have high safety, the characteristics that easy for installation, cost is low.
