The seat body comprises a seat support assembly 1 and a backrest assembly, wherein two sides of the rear end of the seat support assembly 1 are fixedly provided with an upward extending adapter 11. The backrest assembly comprises a front backrest 2 and a rear backrest 3, the upper ends of the front backrest 2 and the rear backrest 3 are rotatably connected, the lower ends of the front backrest 2 are rotatably arranged on two adapter pieces 11, and the lower ends of the rear backrest 3 are connected with a traction mechanism 4. Specifically, the lower end of the back rest 3 is rotatably mounted with a bracket 5, and the traction mechanism 4 is used to make the bracket 5 movably assembled to the inside of the automobile back and forth.

The seat body has a sitting posture mode in which the front backrest 2 and the rear backrest 3 are arranged to overlap, and a lying posture mode in which the traction mechanism 4 is movable in the seat front-rear direction, with reference to fig. 3. Referring again to fig. 6 and 7, the traction mechanism 4 is moved rearward to enable control of the rearward deployment of the front and rear backrests 2, 3 to switch the seat body from the sitting to lying mode.

Based on the above structural design, when the seat body is required to be deformed into a bed, the seat support assembly 1 is kept fixed, the traction mechanism 4 controls the support 5 to slide backwards, namely drives the lower end of the back rest 3 to move backwards, and as the lower end of the back rest 3 is rotationally connected with the support 5, the upper end of the front rest 2 is rotationally connected with the upper end of the back rest 3, and the lower end of the front rest 2 is rotationally connected with the rear end of the seat support assembly 1, in the process that the support 5 drives the lower end of the back rest 3 to move backwards, the back rest 3 can be pulled to slide backwards and the back rest 3 rotates forwards around the support 5, and meanwhile, the front rest 2 is driven to rotate backwards around the adapter 11 until the front rest 2 and the back rest 3 are completely flattened, so that the seat is deformed into the bed, and the seat has the technical advantages of convenient operation and proper overall structure size, and can meet the support length and comfort level of a user.

Referring again to fig. 1 and 3, the traction mechanism 4 includes a guide rail 41 fixedly assembled to the inside of the automobile, and a slider 42 slidably disposed on the guide rail 41, the support 5 is fixedly connected to the slider 42, and the traction mechanism 4 is provided with a driving assembly 6, and the driving assembly 6 can drive the slider 42 to slide back and forth. In this embodiment, the support 5 is disposed in the middle of the lower end of the back rest 3, so as to ensure that the support 5 can be stressed uniformly when the back rest 3 is pulled to move.

As shown in fig. 1, the upper end of the backrest assembly is provided with a first transfer component 8, two ends of the first transfer component 8 are respectively hinged with the upper end of the front backrest 2 and the upper end of the rear backrest 3, and as can be seen from fig. 4, the backrest assembly is provided with a recliner 7, and the recliner 7 can drive the front backrest 2 to rotate back and forth. Referring to fig. 3, in the sitting mode state, the front backrest 2, the first transfer member 8, the rear backrest 3, and the "whole body formed by the seat support assembly 1 and the support 5" form a four-bar linkage structure, and the front backrest 2 is driven to rotate, so that the rear backrest 3 can be driven to rotate synchronously, thereby achieving the purpose of adjusting the inclination angle of the backrest in a small range, and further meeting the comfort requirement of the user in the sitting state.

As shown in fig. 4, in the present embodiment, the recliner 7 is disposed between the front backrest 2 and the two adapters 11, and in the sitting position of the seat, the recliner 7 drives the front backrest 2 to rotate back and forth, so as to drive the rear backrest 3 to rotate synchronously. In addition, the seat body is in a lying mode, the angle adjuster 7 drives the front backrest 2 to rotate upwards, the back backrest 3 can be driven to rotate upwards, the support 5 and the sliding block 42 are pulled to slide forwards, and therefore the seat body is converted from the lying mode to the sitting mode, and convenience in operation is further improved.

Referring to fig. 1 and 2, a first cross bar 21 is disposed at the upper end of the front backrest 2, a second cross bar 31 is disposed at the upper end of the rear backrest 3, and, in conjunction with fig. 5, the first adapter member 8 has a block structure, and two connecting through holes 81 are disposed at two ends of the length direction of the first adapter member, and the first cross bar 21 and the second cross bar 31 are respectively rotatably connected with the two connecting through holes 81. In this embodiment, the first adapter member 8 is a split structure, which is formed by fastening an upper portion and a lower portion, so as to facilitate assembly.

Referring again to fig. 2, a torsion spring a is provided between the first transfer member 8 and the front backrest 2, the torsion spring a applying a force to deform the angle between the first transfer member 8 and the front backrest 2. In this way, considering that the seat body is in the sitting posture mode, the torsion spring a can eliminate the gap between the first transfer component 8 and the front backrest 2, ensure that the front backrest 2 and the rear backrest 3 are always tightly connected, and ensure the stability of the whole structure. When the seat body is retracted from the lying mode to the sitting mode, the torsion spring a can ensure that the connecting position of the front backrest 2 and the rear backrest 3 has an upward rotating pre-thrust, and the stability and the reliability of combination of the front backrest 2 and the rear backrest 3 are ensured. In the present embodiment, the torsion spring a is located between the first transfer member 8 and the end of the first cross bar 21.

As shown in fig. 1, in order to enhance the reliability of the rotational connection of the front backrest 2 and the rear backrest 3, in the present embodiment, the first transfer members 8 are provided in two sets in number. The two sets of first transfer members 8 are distributed along the width of the backrest assembly. Simultaneously, the torsion springs a are also provided with two groups, and the two groups of torsion springs a are respectively arranged at two ends of the first cross rod 21.

Example two

The difference between the present embodiment and the first embodiment is the switching structure between the upper ends of the front backrest 2 and the rear backrest 3, which is specifically as follows:

Referring to fig. 8, in this embodiment, a supporting cross bar 22 inclined backward is provided at the upper end of the front backrest 2, a second adapting member 9 extending obliquely upward is provided at the upper end of the rear backrest 3, and one end of the second adapting member 9 away from the rear backrest 3 is rotatably connected to the supporting cross bar 22. So designed, the traction mechanism 4 drives the support 5 to move backwards, and the front backrest 2 and the rear backrest 3 can be controlled to be unfolded backwards (refer to fig. 9).

Finally, it should be noted that the above description is only a preferred embodiment of the present utility model, and that many similar changes can be made by those skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
