Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, in particular to a seat cushion with staggered upper and lower layers. Background Art

[0002] A seat cushion is a cushion placed on a chair or stool, usually designed to increase comfort, relieve pressure, or protect the user from hard surfaces. Cushions can be made from a variety of different materials, such as sponge, memory foam, and fabric, and can come in a variety of shapes and sizes to suit different chairs and uses.

[0003] Hollow gels are becoming increasingly popular in the seat cushion market because they have more properties than sponges. For example, hollow gels can achieve different supporting forces in different parts of the body. The supporting force of the upper layer of hollow gel can differ by more than 10 times that of the lower layer. This is beneficial for drivers and some special groups of people, and it also has better breathability. However, hollowing out the gel will reduce its firmness and make it inconvenient to evenly disperse the pressure.

[0004] Therefore, it is necessary to provide a seat cushion with staggered upper and lower layers to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the present utility model is to provide a seat cushion with staggered upper and lower layers to solve the problems in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cushion with staggered upper and lower layers comprises a frame, wherein a first connecting rib and a second connecting rib are arranged in the frame, the first connecting rib and the second connecting rib are arranged alternately, and a contact area between the first connecting rib and the second connecting rib is set as an alternate area.

[0008] As a further solution of the utility model, the connecting ribs 1 and 2 are both configured to be composed of a plurality of hexagonal frames.

[0009] As a further solution of the utility model, the frame, the first connecting rib and the second connecting rib are all made of gel injection molding in one piece.

[0010] As a further solution of the utility model, the end surface dimensions of the connecting ribs 1 and 2 close to the interlaced area are respectively larger than the end surface dimensions of the connecting ribs 1 and 2 away from the interlaced area.

[0011] As a further solution of the utility model, the thickness dimension of the connecting rib 1 is greater than the thickness dimension of the connecting rib 2.

[0012] As a further solution of the utility model, the interlaced area includes a connecting groove located at one end of the connecting rib 1 close to the connecting rib 2, and the connecting groove is in contact with the outer wall of the connecting rib 2.

[0013] As a further solution of the utility model, the opening size of the connecting groove is smaller than the bottom size of the connecting groove.

[0014] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0015] The utility model can increase more stress points than the structure with upper and lower aligned structures by staggered mutually arranged connection ribs 1 and 2, so as to facilitate uniform stress. The end surface dimensions of the connection ribs 1 and 2 close to the staggered area are respectively larger than the end surface dimensions of the connection ribs 1 and 2 far from the staggered area, so as to expand the contact area and facilitate demoulding. The connection grooves can form barbs in the staggered area of ​​the connection ribs 1 and 2, so that the connection between the connection ribs 1 and 2 is more firmly connected, and has the effects of uniform stress, expanded contact area, convenient demoulding and firm and reliable connection.

[0016] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The seat cushion with staggered upper and lower layers includes a frame, in which connecting ribs 1 and 2 are arranged, the connecting ribs 1 and 2 are staggered, and the contact area between the connecting ribs 1 and 2 is set as a staggered area.

[0025] In this embodiment, the connecting ribs 1 and 2 are both configured to be composed of a plurality of hexagonal frames, the frame, connecting ribs 1 and 2 are all made by gel injection molding, the end face dimensions of the connecting ribs 1 and 2 close to the interlaced area are respectively larger than the end face dimensions of the connecting ribs 1 and 2 away from the interlaced area, the thickness dimension of the connecting rib 1 is larger than the thickness dimension of the connecting rib 2, the interlaced area includes a connecting groove located at one end of the connecting rib 1 close to the connecting rib 2, the connecting groove is fitted with the outer wall of the connecting rib 2, the opening dimension of the connecting groove is smaller than the bottom dimension of the connecting groove, wherein the connecting ribs 1 and 2 can be configured to be other different shapes, including but not limited to pentagons and triangles.

[0026] By staggering the connecting ribs 1 and 2, more stress points can be added than the structure aligned up and down, so as to facilitate uniform stress. By making the end surface dimensions of the connecting ribs 1 and 2 close to the staggered area larger than the end surface dimensions of the connecting ribs 1 and 2 away from the staggered area, the contact area can be expanded to facilitate demoulding. By setting the connecting groove, a barb can be formed in the staggered area of ​​the connecting ribs 1 and 2, so that the connection between the connecting ribs 1 and 2 is more secure, and the effects of uniform stress, expanded contact area, convenient demoulding and firm and reliable connection are achieved.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
