Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a seat cushion assembly and a seat. Background Technology

[0002] Currently, the seat cushion components of some high-end seats typically include a rigid frame, flexible filling, and a leather cover. The flexible filling is usually made of molded cotton, and the leather cover is wrapped around the molded cotton. The rigid frame provides a certain degree of support to the seat cushion component. When the seat is in use, the molded cotton is compressed and deformed to maintain a high level of comfort for the seat cushion component.

[0003] Some existing seat cushion assemblies, to ensure the integrity of the assembly, use a rigid frame with fixing steel bars around the perimeter. These steel bars are positioned at the edge of the shaping cotton, and C-shaped fixing rings are attached to the steel bars. A fixing strip is also installed on the leather cover at the corresponding edge of the shaping cotton. The fixing strip is inserted into the fixing ring, thus securing the leather cover to the rigid frame when it is placed over the shaping cotton. However, in these existing seat cushion assemblies, the steel bars located at the edges of the cushion cause contact between the user and the steel bars, resulting in poor seat comfort. Furthermore, the addition of fixing steel bars, C-shaped fixing rings, and fixing strips to the leather cover makes the seat cushion assembly structurally complex and cumbersome to assemble.

[0030] like Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a seat cushion assembly for a chair, which includes a rigid support 10, a shaping cotton 20, a leather cover 30, and a bottom fabric 40. The shaping cotton 20 includes a bottom surface 201 and a top support surface 202 opposite to the bottom surface 201. The top support surface 202 is configured to match the shape of the human buttocks and thighs to provide flexible support for the human buttocks and thighs. An upwardly recessed recess 21 is provided on the bottom surface 201 of the shaping cotton 20. The upwardly recessed recess 21 forms a side wall 24 on both sides of the shaping cotton 20 and an end wall 25 on both ends of the shaping cotton 20. Two upwardly recessed grooves 22 are provided on the top surface 211 of the recess 21. The two grooves 22 are located inside the side walls 24 respectively. The grooves 22 extend in the front-back direction, that is, the length direction of the grooves 22 is consistent with the front-back direction. The grooves 22 extend approximately from the front end to the rear end of the shaping cotton 20. The rigid support 10 includes a base frame 101 and two side support portions 102. The side support portions 102 are located on both sides of the base frame 101 and extend upward. The base frame 101 is embedded in the recess 21 of the shaping cotton 20. The two side support portions 102 are embedded in two grooves 22. The side support portions 102 are supported on the inner surface of the side wall 24, and the two ends of the side support portions 102 are supported on the inner surfaces of the end wall 25 and the end wall 26, respectively. The leather sleeve 30 is fitted over the outside of the shaping cotton 20, completely wrapping the shaping cotton 20. The bottom fabric 40 covers the bottom surface 201 of the shaping cotton 20, and the edge of the bottom fabric 40 is connected to the periphery of the leather sleeve 30 by a connector.

[0031] In this invention, recesses 21 and grooves 22 are provided on the shaping cotton 20. The bottom frame 101 and side support 102 of the rigid bracket 10 are respectively placed in the recesses 21 and grooves 22. The rigid bracket 10 provides rigid support to the bottom and sides of the shaping cotton 20, preventing the rigid bracket 10 from protruding from the outer contour surface of the shaping cotton 20. When the seat cushion assembly is in use, the user's body will not come into contact with the rigid bracket 10, thereby improving the comfort of the seat cushion assembly. During assembly, the rigid bracket 10 is embedded in the recesses 21 and grooves 22. In step 2, the side support parts 102 on both sides of the rigid bracket 10 provide support for the shaping cotton 20 on both sides, ensuring that the shaping cotton 20 will not be deformed too much due to compression. The leather cover 30 can be directly put on the outside of the shaping cotton 20. Finally, the bottom cloth 40 is connected to the leather cover 30 through the connector, and the assembly of the seat cushion assembly can be completed. There is no need to configure the fixing steel strip, C-shaped fixing ring, etc. on the seat cushion assembly for connecting the leather cover 30, which simplifies the structure of the seat cushion assembly, makes the seat cushion assembly easier to assemble, and improves the assembly efficiency.

[0032] It should be noted that the aforementioned connector can be a zipper, with the two sides of the zipper connected to the periphery of the base fabric 40 and the periphery of the leather sleeve 30, respectively. In other embodiments, the connector can be Velcro or snap fasteners.

[0033] The base frame 101 of the rigid support 10 includes two longitudinal beams 11 extending forward and backward, a transverse beam 12 extending laterally, and a transverse beam 13 extending laterally. The two longitudinal beams 11 are located on both sides of the base frame 101, the transverse beam 12 is located at the front end of the base frame 101, and the transverse beam 13 is located at the rear end of the base frame 101. The two ends of the transverse beams 12 and 13 are fixedly connected to the two longitudinal beams 11. The two longitudinal beams 11 and the transverse beam 12 are integrally formed. They can be formed by bending a steel pipe with a circular cross-section. The two ends of the transverse beam 13 are welded to the rear ends of the two longitudinal beams 11. The longitudinal beams 11 and the transverse beam 12 are set to have a circular cross-section, so that the contact position between the rigid support 10 and the shaping cotton 20 is relatively rounded, avoiding damage to the shaping cotton 20 by the rigid support 10. Two side support portions 102 are located above the two longitudinal beams 11 respectively. Each side support portion 102 includes a support rod 14 located above the longitudinal beam 11. The cross-section of the support rod 14 is circular. Specifically, the support rod 14 can be made of steel pipe of the same specifications as the longitudinal beam 11. The front end of the support rod 14 is bent downward to form a connecting section 141. The lower end of the connecting section 141 is welded and fixed to the front end of the longitudinal beam 11, so that the support rod 14 and the longitudinal beam 11 are spaced at a certain distance, so that the side support portion 102 has a certain height, so that the side support portion 102 can be embedded in the groove 22 through the recess 21, so that the top of the support rod 14 abuts against the top surface 211 of the groove 22. The length of the support rod 14 is equivalent to the length of the groove 22, so that the connecting section 141 abuts against the front end face of the groove 22.

[0034] A support plate 16 is provided between the rear end of the support rod 14 and the rear end of the longitudinal beam 11. The upper and lower ends of the support plate 16 are welded and fixed to the support rod 14 and the longitudinal beam 11, respectively. The support plate 16 is made of steel plate and is bent into a C-shape with the opening facing inward. After the upper and lower ends of the support plate 16 are welded to the support rod 14 and the longitudinal beam 11, at least a portion of the outer side of the support plate 16 protrudes beyond the outer edges of the support rod 14 and the longitudinal beam 11. The outer edge of the support rod 14 abuts against... On the outer wall of the groove 22, the outer edge of the longitudinal beam 11 abuts against the side wall 24. A recessed groove 27 is provided on the outer wall of the groove 22, so that the protruding part of the support plate 16 is embedded in the groove 27. In this way, the strength of the side support 102 is improved by the support plate 16. At the same time, the support plate 16 is locked in the groove 27 to position the shaping cotton 20 and the rigid bracket 10. When the leather sleeve 30 is put on the outside of the shaping cotton 20, it prevents the shaping cotton 20 from falling off the rigid bracket 10.

[0035] Two or more elastic support members 15 are provided on the bottom frame 101. These two or more elastic support members 15 are arranged in the front-to-back direction. The elastic support members 15 extend from one of the longitudinal beams 11 to the other longitudinal beam 11. The upper surface of the elastic support member 15 abuts against the top surface 211 of the recess 21. The elastic support member 15 provides support for the shaping cotton 20. When the shaping cotton 20 is compressed and deformed downward, it squeezes the elastic support member 15 downward, causing the elastic support member 15 to deform downward. The elastic stress generated by the elastic support member 15 gradually increases until it reaches a balance with the downward pressure on the shaping cotton 20. In this way, the excessive deformation of the shaping cotton 20 can be avoided, which plays a protective role for the shaping cotton 20 and improves the comfort of the seat cushion assembly.

[0036] The elastic support 15 includes an elastic sheet 151 and two hooks 152. The two hooks 152 are respectively connected to the two ends of the elastic sheet 151 and are respectively hooked onto the two longitudinal beams 11. The elastic sheet 151 can be made of elastic cloth strips or elastic metal sheets. The width W1 of the elastic sheet 151 is set in the range of 20 to 40 mm, preferably 30 mm. The spacing W2 between two adjacent elastic sheets 151 is 5 to 7 times that of W1 to ensure that the elastic sheets 151 are reasonably distributed in the front-back direction so as to provide better protection for the shaping cotton 20. A reinforcing beam 17 is provided between adjacent elastic support members 15. The two ends of the reinforcing beam 17 are fixed to the bottom of the two longitudinal beams 11, thus forming a gap of width D between the upper part of the reinforcing beam 17 and the top surface 211 of the recess 21, where D is greater than or equal to 8mm. By setting this gap D, the shaping cotton 20 can deform downwards sufficiently, avoiding interference between the shaping cotton 20 and the reinforcing beam 17. The top surface 211 of the recess 21 is also provided with multiple upwardly recessed receiving grooves 23. A massage mechanism is installed on the reinforcing beam 17, and the massage head of the massage mechanism is housed in the receiving groove 23, thus enabling the seat cushion assembly to have an active massage function.

[0037] The seat of this utility model includes the seat cushion assembly of the aforementioned seat. The other structures of the seat are the same as those in the prior art and will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
