Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

Fig. 1 is a perspective view of the utility model discloses cushion of adjustable lumbar support height, fig. 2 is the utility model discloses back structure schematic diagram of cushion of adjustable lumbar support height, fig. 3 is the utility model discloses use state diagram of cushion of adjustable lumbar support height, please refer to fig. 1 to fig. 3 and show, show the embodiment of a preferred, the cushion of adjustable lumbar support height that shows, include: cushion main part 1, waist pillow 2, connecting band 3 and magic subsides 4.

The surface of one side of cushion main part 1 is the cambered surface 5 of indent, and the middle part of cambered surface 5 is equipped with waist pillow 2, and the opposite side of cushion main part 1 is equipped with magic subsides 4 on the surface, and waist pillow 2 passes through connecting band 3 and is connected with magic subsides 4. As shown in fig. 1, the front surface of the back cushion main body 1 is an inward concave cambered surface 5, and the magic tape 4 is arranged on the back surface of the back cushion main body 1; the waist pillow 2 is attached to the cambered surface 5. When using, the front laminating of cushion main part 1 is at user's waist, and the back laminating of cushion main part 1 is on the seat, and waist pillow 2 is used for supporting user's waist, can adjust waist pillow 2's height through the position of adjusting magic subsides 4, can satisfy different crowds' size, height, the different problem of waist custom. The overall shape and appearance of the cushion main body 1 are relatively mellow, and the cambered surface on the cushion main body 1 is completely attached to the physiological curve of the back of a human body.

Further, as a preferred embodiment, the upper ends of the two sides of the cushion main body 1 are both protruded upwards to form two first arc-shaped protrusions 6, an arc-shaped slot 7 is formed between the two first arc-shaped protrusions 6, and the connecting band 3 is clamped in the arc-shaped slot 7. As shown in fig. 3, when in use, the first arc-shaped protrusion 6 is attached to the back of the user, which can support the back of the user and relieve the pressure on the back.
