Description

A kind of rear seat back latch hook

Technical field

The utility model is related to automobile technical field, and more particularly to a kind of rear seat back latch hook.

Background technology

With the fast development in epoch, the relevant knowledge of automobile is increasingly understood in information age consumer.Disappear now Expense person is more than focusing on appearance and modeling, comfortableness and the configuration of automobile, and the security performance to automobile requires also more and more higher.Except Increase air bag, to protect driver and occupant, the intensity of seat itself will also be strengthened.

In the past, back seat was generally locked on vehicle body by people by the latch hook with yi word pattern locking bar, to reduce heel row occupant Injury values.But the base plate of the latch hook is not fitted on vehicle body completely, it is impossible to withstood shocks well, and because locking bar is Yi word pattern structure, it is also easier to deformation.

Utility model content

In view of this, the utility model provides one kind and can preferably withstood shocks in collision process, and deflection is smaller, And then reduce the rear seat back latch hook of heel row occupant injury value.

To solve the above problems, the utility model provides a kind of rear seat back latch hook, including locking bar and base plate, the lock Bar is in " U " type, and its two ends is fixed on the base plate, and the base plate is used to being fixed on body of a motor car, and with body of a motor car it Between form the space of closing.

Further, the base plate is provided with the riveted holes for being used for passing through for the locking bar, and being located at for the locking bar is described The both sides up and down of part in riveted holes are respectively formed with the first stop section and the second stop section, first stop section and described Second stop section by the base plate tightly sandwiched therebetween.

Further, first stop section is tapered, and second stop section is in disk form.

Further, the base plate include two installing plates, from described two installing plates corresponding sides to away from Automobile Two connecting plates of the direction extension of body and the fixed plate being connected with two described connecting plates, the sky of the closing Between be formed between the connecting plate, the fixed plate and the body of a motor car.

Further, the installing plate and the fixed plate are parallel to each other.

Further, the distance between described two connecting plates at the installing plate from gradually increasing at the fixed plate Plus.

Further, a bolt hole for being used to fix base plate, described two are respectively provided with two described installing plates Bolt hole is located at two of base plate diagonally.

Further, a diameter of 9mm of the locking bar.

By rear seat back latch hook of the present utility model, can be easy to its in collision process stress evenly, deflection It is smaller, its deflection is controlled within 10mm, and then can preferably reduce heel row occupant injury value.

Brief description of the drawings

Fig. 1 is the schematic diagram of the rear seat back latch hook of an embodiment of the present utility model.

Fig. 2 is schematic cross-sectional views of the Fig. 1 along II-II lines.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further elaborated.It should be appreciated that this place is retouched The specific embodiment stated only to explain the utility model, is not used to limit the utility model.

Fig. 1 is the schematic diagram of the rear seat back latch hook of an embodiment of the present utility model.As shown in figure 1, in the implementation In example, rear seat back latch hook includes locking bar 1 and base plate 2.

Locking bar 1 is used to coordinate with the backrest lock body of auto rear seat.From the appearance, locking bar 1 is in " U " type structure, diameter , can be with general during such later stage new car model development for 9mm.As shown in Fig. 2 two ends of locking bar 1 are formed by cold heading technique There are two pyramidal structures, then by hot riveting technique, be connected after the two ends of locking bar 1 are pressed into riveted holes 26 described later with base plate 2, After rivet hot, locking bar 1 be located at riveted holes 26 in part be fitted close with riveted holes 26, and locking bar 1 be located at riveted holes 26 The both sides up and down of interior part are respectively formed with the first stop section 11 and discoidal second stop section 12 of taper, the first block The size on the surface contacted with base plate 2 of the stop section 12 of portion 11 and second is all higher than the size of riveted holes 26.Due to using rivet hot Technique so that the first stop section 11 and the second stop section 12 tightly press from both sides base plate 2 between them, make locking bar 1 and base plate 2 it Between have higher bonding strength so that locking bar 1 can preferably withstand shocks, deflection is smaller.Also, due to locking bar 1 Using " U " type structure, make it relative to yi word pattern structure, can preferably withstand shocks, deflection is smaller, controllable back seat is leaned on The deflection of lockback hook is within 10mm.

As shown in Figures 1 and 2, base plate 2 is enclosed construction, and it includes two installing plates 21, pair by two installing plates 21 The fixed plate 23 that the inner side of Ying Bianxiang base plates 2 tilts two connecting plates 22 of extension and is connected with two connecting plates 22.Gu Fixed board 23 is parallel with installing plate 21, and the side of the remote vehicle body positioned at installing plate 21, and the distance between connecting plate 22 is by solid To gradually increasing at installing plate 21 at fixed board 23, being formed between the connecting plate 22 of base plate 2, fixed plate 23 and body of a motor car can With the space 24 for the second stop section 12 for accommodating locking bar 1.Two bolts hole 25, fixed plate 23 are respectively equipped with two installing plates 21 Provided with two riveted holes 26.Two bolts hole 25 are located at two of base plate 2 diagonally, thus, can be the bottom of by by two bolts Plate 2 is securely seated between on vehicle body.Due to the design feature of base plate 2, base plate 2 can be fixed on automobile in enclosed mode On vehicle body, the space 24 of closing is formed between base plate 2 and vehicle body, due to enclosed space compared to for open space more Plus it is firm, therefore can make the stress of base plate 2 evenly, deflection is also smaller.

The preferred production technology with regard to the rear seat back latch hook of the embodiment is described in detail below.

First, base plate 2 is obtained using 16MnCr5 steel plates as raw material are stamped, its hardness is preferably HRC40~43.With SCM435 is that raw material obtain locking bar 1 through cold-heading, and its hardness is preferably HRC35~38.Again by hot riveting technique, by the He of locking bar 1 Base plate 2 is riveted, and finally obtains required product.

When verifying the deflection of rear seat back latch hook of the present utility model, back seat is leaned on by 2 bolts first Lockback hook is arranged on body side wall, reassembles decorative panel and rear seat back under luggage compartment left side decorative panel, left back post, finally Rear seat back latch hook and rear seat back lock body are coordinated.

Then 2 weight 18Kg sample block is placed in luggage case, luggage case impact test is carried out to product, measurement back seat is leaned on The deflection of lockback hook.Through experiment, it is known that its deflection is within 10mm, so as to ensure back seat head pillow frame and backrest frames Deflection within the scope of laws and regulations requirement.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
