The comfort level of the automobile seat directly influences the riding experience of a passenger and even influences the safety of the passenger, so that a head and neck supporting device (such as a head and neck supporting device) is additionally arranged on the automobile seat to improve the use comfort level of the passenger. However, after the current head and neck support device is installed on the seat, the height of the head and neck support device can only be adjusted generally, and the angle adjustment cannot be performed, the height adjustment step is complicated, the processes of unlocking, adjusting, locking and the like need to be performed manually, the use is quite unchanged, and the user experience is greatly reduced.

In view of the above, the present application provides a neck support device 100, which can be applied to a seat, such as an office chair, a car seat, a massage chair, etc., for supporting the head and neck of a user to improve the comfort of the user. In the following embodiments and illustrations of the present application, the description is given by way of example of a car seat, and should not be construed as a specific limitation of the neck support apparatus 100.

Referring to fig. 1 and 2, the present embodiment provides a head and neck support device 100, which includes a support rod 10, an adjusting member 30 and a support body 50. The support bar 10 is used for being mounted on a seat (e.g., a headrest bar of an automobile seat); the adjusting member 30 is rotatably mounted on the supporting rod 10 (the rotating direction of the adjusting member 30 is shown by arrow B in fig. 1); the supporting body 50 is slidably connected to the adjusting member 30 and can move back and forth along a first direction (as shown by arrow a in fig. 1) relative to the adjusting member 30 and the supporting rod 10 to adjust the position of the supporting body 50 in the first direction; when the adjusting member 30 rotates relative to the supporting rod 10, the supporting body 50 is driven to rotate relative to the supporting rod 10, so as to adjust the angle of the supporting body 50, wherein the first direction is perpendicular to the axis of the adjusting member 30 (as shown by the dotted line O-O in fig. 1).

The supporting rod 10 is used for being installed on a seat; when the neck support device 100 is mounted on a car seat, the support rod 10 can be fixedly connected with the car seat; the support bar 10 may also be removably attached to a car seat. The support bar 10 of the neck support device 10 can also be mounted to the vehicle seat or the headrest bar of the vehicle seat by other means.

The adjusting member 30 is rotatably mounted on the supporting rod 10, and the adjusting member 30 may be directly rotatably mounted on the supporting rod 10 or may be rotatably mounted on the supporting rod 10 by other components (e.g., a positioning mechanism described below).

When the head and neck supporting device 100 is installed on a car seat, the supporting rod 10 may be perpendicular to the backrest of the seat, and of course, the supporting rod 10 may also be disposed to be inclined with respect to the backrest of the seat, and the application is not particularly limited. The support body 50 may be in a vertical orientation or at an acute angle to the vertical, and the axis may be in a horizontal orientation. When the user does on the seat, user's neck and head are close to support body 50, and the user can promote support body 50 through the activity of head and neck and remove along first direction to make support body 50 can be better support user's head and neck, thereby use the user's of different heights head and neck. The angle of the supporting body 50 that different users like is different, and when the user needs to rest on the car, the comfortable angle of the supporting body 50 is also different, and when the user needs to adjust the angle of the supporting body 50, the supporting body 50 can drive the adjusting member 30 to rotate relative to the supporting rod 10 by the force (such as pressing) of the head and the neck, so as to adjust the angle of the supporting body 50 and the supporting rod 10.

The neck support device 100 according to the embodiment of the present application includes a support bar 10, an adjusting member 30, and a support body 50. The supporting body 50 can move along the first direction relative to the supporting rod 10 and the adjusting piece 30, so that the head and neck supporting device 100 can adapt to users with different heights, the height adjustment does not need manual intervention, the height adjustment of the supporting body 50 relative to the seat can be completed only by depending on the neck and the head, and the adjusting method is simple, convenient and quick. In addition, the supporting body 50 can rotate relative to the supporting rod 10 under the driving of the adjusting part 30, so that the supporting body 50 and the supporting rod 10 can form different included angles, the requirements of users on different angles of the supporting body 50 are met, the adjustment of the angle of the supporting body 50 relative to the seat can be completed only by depending on the neck and the head, and the adjusting method is simple, convenient and rapid. From this, the head and neck strutting arrangement 100 of this application embodiment need not manual operation, can be in two dimensions self-adaptation regulation support body 50's position and angle, improvement user's comfort level and experience that can be better.

Referring to fig. 3 and 4, in some embodiments, the supporting rod 10 includes a first rod 11 and a second rod 13, the second rod 13 is at least partially sleeved on the first rod 11, the second rod 13 is rotatably connected to the adjusting member 30, the second rod 13 can move back and forth relative to the first rod 11 along a second direction (as shown by an arrow C in fig. 3) to adjust a position of the supporting body 50 in the second direction, the first rod 11 is configured to be detachably mounted on the seat, wherein the first direction is different from the second direction, and the second direction is perpendicular to the axis. When the head and neck of the user is close to the support body 50, the distance of the second rod 13 moving towards the first rod 11 can be adjusted according to the force applied by the head and neck to the support body 50, so as to adjust the horizontal position of the support body 50 relative to the seat. Therefore, when the head and neck supporting device 100 is installed on a seat, not only the height of the supporting body 50 in the vertical direction can be adjusted, but also the angles of the supporting body 50 in the vertical direction and the horizontal direction can be adjusted, and the positions of the front and the rear of the supporting body 50 (i.e., the positions in the horizontal direction) can be adjusted, so that the head and neck supporting device 100 can adaptively adjust the positions and the angles of the supporting body 50 in three dimensions without manual operation, the adjusting method is simple, convenient and rapid, and the comfort of a user can be better improved.

The second direction is perpendicular to the axis, and specifically, the second direction is an extending direction of the supporting rod 10, in other words, the second direction is an arrangement direction of the first rod 11 and the second rod 13.

Referring to fig. 5, the first rod 11 includes a first sub-rod 111, a second sub-rod 113, a first locking element 115, a second locking element 116, and a resilient element 117.
