Description
Technical Field
The utility model relates to a car seat field especially relates to a flat formula of lying seat device of compact car.
Background
The automobile seat plays a particularly important role in driving, as an important part of an automobile, in terms of comfort. Particularly, in long-distance travel, after a driver drives a vehicle for a long time, eyes and body of the driver are tired, so that the driver needs to stop the vehicle to have a proper rest so as to ensure the safety of continuous driving.
Due to the limitation of the space in the vehicle, when a driver needs to have a rest properly, the back of the driver seat can only be placed backwards to about 140-150 degrees due to the headrest, and the function of lying down completely cannot be realized, so that the driver can only lie in half to have a rest in the vehicle, and for the driver with a high height, the legs of the driver cannot be unfolded completely, and the comfort is poor.
The device that solves the car seat at present and lie flat also has a lot, and wherein, Ordos city ordinary science and technology ltd has proposed one kind and has adjusted the car seat (patent number CN 206067571U) that the formula is used for the sleep, and this seat device is through setting up electric telescopic handle, fly leaf and threaded rod, puts the back flatly the back, drives the fly leaf motion through electric telescopic handle to drive the headrest motion, reached the purpose of adjusting headrest position. However, the adjustment only solves the problem that the position and height of the headrest cannot be adjusted through a series of devices, and the device cannot meet the requirement to achieve the lying degree. The device fixes the headrest on the roof through the support, separates the headrest and the back cushion, thereby reduces the height of the back cushion of the automobile seat, and simultaneously, the cushion and the back cushion are connected through a rotating mechanism, so that the back cushion and the cushion can be connected into a plane. However, when a driver needs to rest by reversely viewing the device, the cushion and the backrest can be presented as a plane, but the driver is in headrest on the roof, so that the risk of falling and injuring the driver exists, and the driver lacks a headrest when resting, so that the comfort is poor.
For other flat-lying type seats, a flat-lying type automobile seat (patent number CN 203888656U) designed outside the south of the yang highway in the chapter tribute region of jiangxi province, Jiangxi province is provided, a headrest support is fixed below the headrest of the seat and is placed in a support groove of a backrest, when the headrest support is pressed to the lowest position, the headrest can be embedded into the headrest groove, the top and a panel of the backrest are neat, the length of a guide rail is extended forwards, the whole seat can move forwards, and the backrest has enough space to rotate backwards until the seat and the backrest form 180 degrees. However, this design also neglects the importance of the headrest at rest, and when the headrest is inserted into the headrest groove, the hair of the driver is easily caught, which presents a certain risk. The formula of lying car seat that can put down that Jiangxi province Juke's actual industry limited company proposed (patent number CN 205768783U) through adopting articulated back for can turn over downwards when needs lie down, and turn over the angle to needs through stop device and carry on spacingly, simultaneously through the scalable footrest that sets up in the bottom cavity, make the driver also can relax when the body is rested the shank, and is more comfortable. However, the limiting device in this device can only be used for limiting the angle of the backrest, and due to the presence of the headrest, the limiting device can only limit the angle before 150 degrees, and the angle of the backrest can not reach the angle of 180 degrees, so that the function of lying down of the seat can not be realized.
