Description

Adjusting device of middle seat backrest

Technical Field

The utility model belongs to the technical field, refer in particular to an adjusting device of middle backrest.

Background

At present, an automobile is one of the most remarkable human characters in the twentieth century, the life style of people is changed, great contribution is made to material wealth and spiritual civilization of the human society, and an automobile seat is an important part of an automobile body. Automobile seat

The system should provide the desired adjustability for the occupant and comfort for long distance driving, with the rationality of the car seat design and its quality directly affecting the safety and comfort of the occupant.

The seats of the light truck are mainly divided into two types, wherein one type is only two seats for a main driver and a subsidiary driver; the other is a main and auxiliary driver and a middle seat, and the number of the main and auxiliary drivers is three. When the middle seat is equipped, the space of the vehicle body is limited, and the use rate of the middle seat is lower than that of the other two seats, so that the middle seat can be folded when being idle, and the space is better utilized.

Disclosure of Invention

The utility model aims at solving the existing problems and providing an adjusting device of a middle seat backrest, which has simple structure, saves space and can effectively solve the problems in the prior art.

The purpose of the utility model is realized like this:

the utility model provides an adjusting device of middle seat back, is including setting up in the grudging post of middle seat rear end, wears to be equipped with the articulated shaft on the grudging post, and the one end of articulated shaft articulates there is back skeleton, and the cover is equipped with the angle modulation ware on the articulated shaft, the other end of articulated shaft has set firmly the angle modulation handle, the shaping has a plurality of concave shape framves on the back skeleton, and the upper end of concave shape frame is provided with the storing box through the mode of pegging graft, when back skeleton edge the articulated shaft rotates, the storing box rotates along with back skeleton rotation direction synchronization.

The utility model discloses further set up to, the lower terminal surface shaping of storing box has a plurality of grafting portion, set up on the concave frame with a plurality of spliced eye of grafting looks adaptation.

The utility model discloses further set up as, the shaping has a storage cylinder and the matter storage lattice of placing object article that are used for placing the beverage in the storage box.

The utility model discloses further set up as, the rotation angle scope of articulated shaft is 0 ~ 90.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

the utility model provides an adjusting device is under the condition that middle seat does not use, through the angle modulation ware, puts the seat flat, the storing box at utilization back rear portion that can be fine, and unblock angle modulation ware only need pull the angle modulation handle a bit, can loosen the angle modulation handle after the unblock and rotate the back, this device simple structure, low in cost, save space, the outward appearance is pleasing to the eye, is fit for promoting on a large scale.

Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which fig. 1-3:

the utility model provides an adjusting device of middle seat back which characterized in that, including setting up in the grudging post 2 of middle seat 1 rear end, wear to be equipped with articulated shaft 3 on the grudging post 2, the one end of articulated shaft 3 articulates there is back skeleton 4, and the cover is equipped with angle modulation ware 5 on the articulated shaft 3, the other end of articulated shaft 3 has set firmly angle modulation handle 6, the shaping has a plurality of concave shape framves 40 on the back skeleton 4, and the upper end of concave shape frame 40 is provided with storing box 7 through the mode of pegging graft, and when back skeleton 4 followed articulated shaft 3 rotates, storing box 7 rotates along with back skeleton 4 rotation direction synchronization.

Preferably, a plurality of inserting parts 70 are formed on the lower end surface of the storage box 7, and a plurality of inserting holes 41 matched with the inserting parts 70 are formed on the concave frame 40.

Preferably, a storage cylinder 71 for storing beverage and a storage case 72 for storing articles are formed in the storage box 7.

Preferably, the hinge shaft 3 has a rotation angle ranging from 0 to 90 °. The angle of the articulated shaft 3 is limited, the limit can be carried out by adopting a mode of arranging a limit point on the articulated column, and the included angle between the limit point and the axis is 90 degrees.

The working principle is as follows:

this middle seat back adjusting device adjusts the back under laborsaving condition, and the space of make full use of seat saves space for the automobile body, and this device simple structure, low in cost, save space, the outward appearance is pleasing to the eye, is fit for promoting on a large scale.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
