Example 1
Referring to fig. 1, the backrest comprises a support frame 1, the support frame 1 having a front face 11 facing a user and a rear face 12 opposite the front face 11, the support frame 1 being configured to form a structural shape of the backrest and to provide a supporting force.
Referring to fig. 1 and 2, at least the front face 11 of the support frame 1 is integrally attached with a plastic member 2, and the plastic member 2 has a hardness smaller than that of the support frame 1. Depending on the product design requirements, plastic part 2 may be attached to both front 11 and back 12 of carrier 1, the surface structure of plastic part 2 being similar to the surface structure of the area of carrier 1 to which it is attached. In this embodiment, the plastic part 2 is a high-resilience sponge, and the support frame 1 is put into a high-resilience sponge forming mold to be formed into a whole with the high-resilience sponge by compression molding.
Referring to fig. 2, the side of the plastic member 2 facing the user is adhered with a comfort member 3 and a slow rebound member 4, wherein the hardness of the comfort member 3 and the slow rebound member 4 is smaller than that of the plastic member 2. The comfort member 3 and the slow rebound member 4 in this embodiment are both sponge, the slow rebound member 4 is a slow rebound sponge, the comfort member 3 is used for supporting the waist and back of the user, the slow rebound member 4 is used for supporting the head of the user, and the hardness of the slow rebound member 4 in this embodiment is smaller than that of the comfort member 3. The hardness of the slow rebound member 4 can be designed to be greater than or equal to the hardness of the comfort member 3 according to the functional requirements of the product.
Referring to fig. 3, the comfort member 3 is cut from a sponge sheet of uniform thickness and then bonded in the corresponding region of the plastic member 2 for fixation. The slow rebound member 4 is adhered and fixed on the plastic member 2 after being molded by the slow rebound sponge and positioned above the position of the comfort member 3 (the direction of the drawing is the using state), and the plastic member 2 is provided with a positioning bulge, so that the slow rebound member 4 is convenient to limit when adhered and fixed.
Example two
Referring to fig. 4-7, the present embodiment is different from the first embodiment in that the connection structure between the comfort member 3 and the plastic member 2 is slightly different.
Referring to fig. 4 and 5, the plastic member 2 has a recess 21, the shape of the comfort member 3 is adapted to the recess 21, and the comfort member 3 is adhered and fixed in the recess 21.
