At present, cars, sport Utility Vehicles (SUVs), utility vehicles, off-road vehicles, buses, motor homes and other vehicles bring convenience to life, work, study and the like of people, and occupy important positions in the travel life of people. The vehicles are various in variety and brands, so that people can select a plurality of vehicles, and the problem that vehicle manufacturers attach more and more importance to the vehicles is solved by how to get favour of the people and improve the competitiveness of the products.

With the increasing consumer demand, vehicles are no longer merely a mobility aid, but more consideration is given to the comfort of the occupants. The driver and the passenger often feel soreness and backache due to long-time driving or sitting, and chronic diseases such as lumbar muscle strain and the like are easily caused for a long time, so that the physical health of people is seriously influenced.

In the related art, many seats of vehicles are equipped with massage devices to massage a driver and passengers, thereby relieving fatigue of the driver and passengers. However, the massage device of the current vehicle seat has poor massage effect and cannot sufficiently relieve fatigue.

Based on this, the present disclosure provides a backrest 100, a seat 10, and a vehicle 1, in which the backrest 100 can massage a user, and the massage effect is good, and fatigue of the user can be better alleviated.

For a better understanding of the backrest 100 and the seat 10 of the present disclosure, a description will be given of the vehicle 1 to which the backrest 100 and the seat 10 are applied.

As shown in fig. 1, there is provided a vehicle 1 including a seat 10 and a moving device 20, the moving device 20 having a seating space 21. The seat 10 is disposed in the seating space 21. The seat 10 includes a back rest 100 and a seat cushion 200, and the back rest 100 is connected to the seat cushion 200. The backrest 100 can massage the user while riding the vehicle 1, and the massage effect is good, thereby better relieving the fatigue of the user. Thereby enabling the chair 10 to massage the user and relieving the user's fatigue.

As shown in fig. 2 and 3, in some embodiments, the backrest 100 includes a backrest body 110 and a massaging device 120. The massage device 120 includes a plurality of massage assemblies 121 disposed at intervals along the second direction on the backrest body 110, and the massage assemblies 121 include a plurality of air bags 103 disposed at intervals along the first direction. At least some of the air cells 103 of the massage assemblies 121 are arranged in a one-to-one correspondence along the second direction to form an air cell group 1211, and the spacing between two adjacent air cells 103 in the air cell group 1211 along the second direction is a first spacing. The first direction and the second direction are intersected. Of the plurality of balloon groups 1211 disposed at intervals in the first direction, the first pitch of at least two balloon groups 1211 is not equal.

As such, when the user leans against the backrest 100, the back of the user is attached to the backrest body 110. The massage assembly 121 is provided at the backrest body 110 and can massage a user leaning against the backrest 100 to relieve fatigue. At least some of the air cells 103 of the plurality of massage assemblies 121 are arranged in a one-to-one correspondence in the second direction, forming an air cell group 1211, and the pitch of adjacent two air cells 103 in the air cell group 1211 in the second direction is a first pitch. Based on the human muscle fiber direction and the nerve trigger point theory, researchers design the first intervals of at least two air bag groups 1211 to be unequal in a plurality of air bag groups 1211 which are arranged at intervals along the first direction, so that the massage effect on users can be improved, and the fatigue of the users can be better relieved. In addition, the massage mode of the air bag 103 adopted by the massage device 120 can improve the massage effect of the user and better relieve the fatigue of the user.

As shown in fig. 4 and 5, the broken line is an air bag set 1211, and the massage device 120 includes a plurality of air bag sets 1211.

The first distance between the air bags 103 and 103 is the distance between the center points of the air bags 103.

As shown in fig. 3, in some embodiments, the first direction is disposed along a height direction of the backrest body 110, and the second direction is disposed along a width direction of the backrest body 110. That is, the first direction is the X direction shown in fig. 3 to 5, and the second direction is the Y direction shown in fig. 3 to 5.

As shown in fig. 2 and 3, in some embodiments, the massage assemblies 121 are symmetrically disposed along a first axis a, a length direction of the first axis a is disposed along a first direction, and the first axis a is disposed in a middle of a width of the backrest body 110. Thus, when the user leans against the backrest 100, the massage assemblies 121 located at both sides of the first axis a massage the back of the user, and the arrangement of the massage assemblies 121 can better relieve the fatigue of the user and the massage effect is better.

The first axis a of the backrest body 110 corresponds to a trunk line of the user, and when the back of the user leans against the backrest 100, the trunk line of the user coincides with the first axis a.

Researchers have also found in practice that the theoretical placement of the massage air bag 103 of the seat 10 is based on analysis of the human muscle fiber travel, as shown in fig. 4 for an involute arrangement, and in fig. 5 for an adduction arrangement, as follows. The choice of which type of arrangement of the massage air-bag 103 of the vehicle seat 10 is used depends on the height and weight of the occupant of the vehicle 1, as well as the styling limitations of the seat 10. An involute arrangement is recommended when the lateral distance (i.e., width in view) of the face of the backrest 100 where the seat 10 is in contact with the back of the user is greater than 315 mm. When the lateral distance (width in view) of the backrest 100 face is less than 295mm, an adduction arrangement is recommended. At a width between 295 and 315mm, an involute arrangement is more preferred if the curvature is smaller and an adduction arrangement if the curvature is larger, depending on the profile of the seat 10.

As shown in fig. 4, in some embodiments, the plurality of massage assemblies 121 includes a first massage assembly 104 and a second massage assembly 105 disposed on the backrest body 110 along a first axis a symmetrically with the first massage assembly 104. In the second direction, the balloon 103 of the first massage assembly 104 forms a balloon set 1211 with the balloon 103 of the second massage assembly 105. The first pitch of the portions increases in size gradually along the first direction. In this way, the massage assemblies 121 are arranged in an involute manner according to the arrangement direction, and the arrangement manner can enable a user with a lateral distance (i.e., width in view) greater than 315mm of the face of the backrest 100 to rest against the backrest 100 more comfortably and with better massage effect.

In some embodiments, the first spacing of the balloon sets 1211 is maintained constant and then gradually increases in a first direction, i.e., in the positive X direction as shown in fig. 4, thereby forming an involute arrangement.
