Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a waist supporting device for a rear seat of an automobile. Background Art

[0002] With the continuous improvement of people's living standards in my country, cars have become the main means of transportation for ordinary people, bringing great convenience to people's travel. However, when the vehicle travels long distances or encounters traffic jams in cities, the driver and passengers in the car need to maintain a sitting position for a long time, which will cause fatigue in the waist. The usual practice is to adjust the angle of the car seat back to make it vertical while supporting the back of the person.

[0003] The single car seat in the existing technology is difficult to meet the driver's needs. When the driver drives the car for a long time, the waist will be suspended in the air, which will increase the fatigue of the user's waist for a long time. Although adjusting the car seat and placing a pillow on the waist can relieve the waist, it will affect the driver's driving space, reduce the driver's driving comfort, and the pillow and waist are prone to deviation during long-term driving.

[0004] A Chinese patent discloses a lumbar support structure for an automobile seat backrest (authorization publication number CN220447715U). This patented technology pulls two sets of fixed jaws outward. During this outward movement, the sliders move away from each other inside the mounting slot, thereby stretching the return springs between the two sets of sliders. The jaws are then moved to the left and right sides of the seat body corresponding to the lumbar position. The restraint on the jaws is then released, allowing them to move closer together and securely connect to the seat body under the action of the return springs, completing installation. This reduces the difficulty of installing and using the lumbar support structure.

[0005] However, it has certain disadvantages: the height of the lumbar support pad cannot be adjusted according to the user's body shape and needs, which causes the lumbar support pad to be too high or too low for some people and cannot provide proper lumbar support. A lumbar support pad that is too high will compress the waist, while a lumbar support pad that is too low cannot provide sufficient support. Both can easily cause waist fatigue or pain. Utility Model Content

[0006] The purpose of the present utility model is to provide a lumbar support device for a rear seat of a car to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0024] See also Figures 1 to 3 In an embodiment of the present invention, a lumbar support device for a rear seat of a car includes a base 1, a lumbar support pad 2 is fixedly connected to the front surface of the base 1, and a plurality of support mechanisms 3 are arranged between the base 1 and the lumbar support pad 2 from left to right, the support mechanism 3 includes a support tube 4, a rear end of the support tube 4 is fixedly connected to the front surface of the base 1, a first spring 5 is fixedly connected to the inner rear surface of the support tube 4, a front end of the first spring 5 is fixedly connected to a support rod 6, the support rod 6 is slidably connected to the inside of the support tube 4, a front end of the support rod 6 is fixedly connected to a support block 7, a front surface of the support block 7 is fixedly connected to an elastic block 8, and the elastic block 8 is fixed to the rear surface of the lumbar support pad 2;

[0025] The base 1 can be placed on the rear seat 18 of the car for use; the lumbar support pad 2 supports the waist of the passenger and reduces the damage to the waist caused by sitting for a long time; it is preferably made of elastic material, such as rubber;

[0026] Looking from left to right (left view), the lumbar support pad 2 is U-shaped;

[0027] The material of the elastic block 8 is preferably rubber or sponge, and the first spring 5 and the elastic block 8 can cushion the passenger's waist.

[0028] exist Figure 1 、 Figure 2 、 Figure 4 and Figure 5The left and right surfaces of the base 1 are both provided with an adjusting mechanism 9, which includes a tooth plate 10. A plurality of first teeth 11 are fixedly connected to the front surface of the tooth plate 10 from top to bottom, and an adjusting member 12 is provided on the outside of the tooth plate 10. The adjusting member 12 includes an adjusting seat 13. The adjusting seat 13 is located on the outside of the tooth plate 10, and the adjusting seat 13 is slidably connected to the left and right surfaces of the tooth plate 10. The end of the base 1 is fixed to the adjusting seat 13, and two hinge blocks 14 are symmetrically fixed at the lower end of the front surface of the adjusting seat 13. An adjusting plate 15 is rotatably connected between the two hinge blocks 14. A second spring 16 is fixed to the upper end of the rear surface of the adjusting plate 15. The rear end of the second spring 16 is fixed to the front surface of the adjusting seat 13, and the second spring 16 is located above the two hinge blocks 14.
