Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

the front direction described in this specification is a seat facing direction generally understood.

Referring to fig. 1 to 3, the pre-installed hooking device for the car seat backrest according to the present invention comprises a backrest 4, a connecting plate 1 and a cushion wall plate 3, wherein the upper part of the connecting plate 1 is connected with the side surface of the lower end of the backrest 4, the front and the rear of the lower part of the connecting plate 1 are respectively provided with a first connecting hole 11 and a second connecting hole 12, correspondingly, the rear part of the cushion wall plate 3 is provided with a third connecting hole 31 and a fourth connecting hole 32, the third connecting hole 31 corresponds to the first connecting hole 11 and is fixedly connected with the first connecting hole through a bolt, and the fourth connecting hole 32 corresponds to the second connecting hole 12 and is fixedly connected with the second connecting hole through a; the coupler device further comprises a prepositioning hook 2 and a prepositioning trunnion 5 corresponding to the prepositioning hook 2, wherein the prepositioning hook 2 is fixedly arranged on the connecting plate 1, correspondingly, the prepositioning trunnion 5 is fixedly arranged on the cushion wall plate 3, the central symmetry plane of the prepositioning hook 2 is parallel to the connecting plate 1, the prepositioning trunnion 5 is perpendicular to the cushion wall plate 3, and the prepositioning trunnion 5 is hung in the prepositioning hook 2.

Optimally, the pre-positioning hook 2 is integrally formed with the connecting plate 1, the pre-positioning hook 2 is arranged at the lower front corner of the connecting plate 1, and the opening faces upwards.

This device mainly must two operative employee cooperations just can accomplish this defect of work and design to this production step "will be in the same place lower connecting plate and cushion wallboard fixed connection" among the prior art, mainly is fixed on prior art's connecting plate 1 and sets up a prepositioning hook 2, correspondingly, fixedly sets up a prepositioning trunnion 5 on cushion wallboard 3. Before the above-mentioned production steps are carried out, the backrest 4 is already connected with the connecting plate 1; when the production steps are carried out, an operator firstly hangs the pre-positioning hook 2 on the pre-positioning trunnion 5, and then holds the lower part of the backrest 4 by one hand and enables the gravity center of the backrest 4 to lean backwards, so that the pre-positioning hook 2 is stably hung on the pre-positioning trunnion 5, when the operator swings the backrest 4 up and down, the backrest 4 rotates around the pre-positioning trunnion 5, when the operator adjusts the backrest 4 to the first connecting hole 11 and the second connecting hole 12 to be respectively aligned with the third connecting hole 31 and the fourth connecting hole 32, the other hand of the operator can insert the bolt and fasten the bolt by a tool. By the aid of the pre-positioning hook 2 and the pre-positioning trunnion 5, the original assembly work completed by matching two operators can be completed easily by only one operator, so that production efficiency is greatly improved, and production cost is reduced.

In actual operation, the position of the pre-positioning hook 2 and the pre-positioning trunnion 5 is required, see fig. 2. Usually, the distance a from the center of the pre-positioning hook 2 to the far end of the rear lower corner of the connecting plate 1 should be greater than the distance B from the pre-positioning trunnion 5 to the bottom of the cushion wall plate 3, so that an operator can firstly hang the pre-positioning hook 2 on the pre-positioning trunnion 5, then loosen the backrest 4 to the workbench, contact and lean against the rear lower corner of the connecting plate 1 on the workbench, and the gravity of the backrest 4 makes a reaction force act on the pre-positioning hook 2 by using the lever system formed by the rear lower corner of the connecting plate 1 as a fulcrum, so that the pre-positioning hook 2 can be firmly hung on the pre-positioning trunnion 5, and the operator can vacate two hands at the moment to prepare for the work before installation and then perform the adjustment and installation process after the preparation work is completed.

The pre-positioning hook 2 can also be arranged with an opening facing downwards, and when an operator hangs the pre-positioning hook 2 on the pre-positioning trunnion 5, the pre-positioning hook 2 can be stably hung on the pre-positioning trunnion 5 only by the gravity of the backrest 4.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, therefore, any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention should be included in the scope of the present invention.
