Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The technical solution of the present application is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 6, the seat body 7 according to the embodiment of the present invention is adapted to be assembled on the seat frame 13, the seat body 7 is formed with a first portion 701 and a second portion 702 having an included angle of 90 ° or more, the seat body 7 has an arc connecting portion 703 connected to the seat frame 13, the arc connecting portion 703 extends along a first direction, a part of the arc connecting portion 703 is disposed on the first portion 701, and another part of the arc connecting portion 703 is disposed on the second portion 702. The seat body 7 is slidably connected to the seat frame 13 in the first direction, and the first portion 701 and the second portion 702 are equal in length.

The utility model discloses seat body 7 fixes seat body 7 on seat skeleton 13 when using, and seat body 7 links to each other with seat skeleton 13 through arc connecting portion. Because seat body 7 is along first direction and seat skeleton 13 sliding connection for when sliding seat body 7 along first direction (for example fore-and-aft direction), can make seat body 7 rotate and predetermine the angle (for example rotate 90 °) and change seat body 7's orientation, realize turning to of seat body 7. For example, when the passenger wants to sit forward, the seat body 7 is slid in a first direction (e.g., a front-rear direction) such that the seat body 7 is positioned forward (as shown in fig. 5), and the first portion 701 serves as a backrest and the second portion 702 serves as a seat cushion. When the passenger wants to sit backward, the seat body 7 is slid in the front-rear direction so that the seat body 7 is disposed backward (as shown in fig. 6), and at this time, the first portion 701 serves as a seat cushion and the second portion 702 serves as a backrest. Wherein the length direction of the first portion 701 coincides with the front-rear direction of the passenger when the first portion 701 serves as a seat cushion, and the length direction of the first portion 701 coincides with the front-rear direction of the passenger when the second portion 702 serves as a seat cushion. The first part 701 and the second part 702 are equal in length so that both the first part 701 and the second part 702 can be adapted to the seat cushion and the backrest, i.e., the first part 701 can be freely switched between the seat cushion function and the backrest function, so that the passenger can have a better comfort both when sitting forward and when sitting backward.

From this, only need along first direction slip seat body 7, can realize turning to of seat body 7 for it is more convenient that the seat body turns to. The utility model discloses seat body 7 is through establishing first portion 701 and second portion 702 to equal length for the passenger is when taking forward and taking backward the travelling comfort all better.

Therefore, the embodiment of the present invention provides a seat body 7 with good steering convenience and riding comfort.

In addition, on one hand, a sitting space for passengers to sit is left in the first direction (for example, the front-back direction), and the sitting space can provide enough activity space for the steering of the seat body 7 without additionally occupying other space in the vehicle cabin, which does not need to reserve additional space for seat adjustment (rotation) in the vehicle compared with the related art in which the steering of the seat body is realized by rotating the seat body along the horizontal direction, so that the occupied space of the seat body 7 is small, and other interior parts are convenient to arrange in the vehicle cabin, so that the vehicle cabin interior trim is richer in shape and more diverse in function, and the user experience is better improved; on the other hand, seat body 7 realizes turning through sliding along first direction for seat body 7 need not move seat body 7 in turning to the in-process, this with realize turning to of seat body through dismouting seat body among the correlation technique and compare, the manpower that can significantly reduce, and can effectively avoid the problem of the fish tail of colliding with of other interior trim parts in the vehicle passenger cabin that causes because of moving seat body 7.

In order to make the technical solution of the present application more easily understood, the technical solution of the present application is further described below by taking as an example that the first direction coincides with the front-back direction, which is shown in fig. 1, 2, 5 and 6.

For example, as shown in fig. 1, 2, 5, and 6, the first portion 701 and the second portion 702 are arranged in the front-rear direction, the first portion 701 is located on the rear side of the second portion 702, the arc-shaped connecting portion 703 is provided at the bottom of the seat body 7, the arc-shaped connecting portion 703 is connected to the seat frame 13, and the front-rear orientation of the seat body 7 is changed by moving the seat body 7 in the front-rear direction.

In some embodiments, the first portion 701 and the second portion 702 are symmetrically arranged with a center line extending in a second direction as a symmetry axis, wherein the second direction is perpendicular to the first direction.
