Description

Technical Field

[0001] The utility model relates to a daily necessity, more specifically, to a seat structure. Background Art

[0002] Recliners are common items in our daily lives. They mainly include a chair frame and a seat fabric. The common way to connect the seat fabric and the chair frame is to weld a number of wires on the chair frame, punch a number of eyelets on the seat fabric, and pass an elastic rope through the wires and eyelets to fix the seat fabric to the chair frame. Welding destroys the coating on the surface of the pipe, and the welding point is prone to rust after use. The elastic rope is prone to lose its elasticity and loses comfort after long-term use. The elastic rope is connected by a whole rope. If any part of the elastic rope is damaged, the connection between the entire seat fabric and the chair frame will fail, which will bring safety hazards to users. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a seat structure, in which the seat frame and the seat cloth are reliably connected, thus avoiding the safety hazards caused by connection failure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a seat structure, including a chair frame and a seat cloth, an elastic belt is arranged on the edge of the seat cloth, and the elastic belt is connected to the chair frame to provide elastic force to the seat cloth.

[0005] The chair frame and the seat fabric are connected by an elastic band, which not only connects the chair frame and the seat fabric together, but also provides elastic force, making it more comfortable for the human body to sit on the seat fabric. The elastic band is wide, and even if it is damaged in a local position, it will not cause the connection of the entire seat fabric to fail. The chair frame and the seat fabric of this seat structure of the patent are reliably connected, avoiding the safety hazards caused by connection failure.

[0006] Preferably, a plurality of elastic bands are arranged at intervals.

[0007] Several elastic bands are arranged at intervals to facilitate the assembly and connection of the seat fabric and the chair frame. Arranging multiple elastic bands allows each position of the seat fabric to be elastic, ensuring riding comfort. Moreover, multiple elastic bands can disperse the tension of the seat fabric, so that the force is applied at multiple points.

[0008] Preferably, the seat fabric comprises a footrest section, a cushion section and a backrest section, and elastic bands are arranged on the left and right sides of the footrest section, the left and right sides of the cushion section, and the left and right sides of the backrest section.

[0009] The seat fabric is divided into three sections, which are adapted to different parts of the human body, conforming to the ergonomic design and making the ride more comfortable. In addition, elastic bands are connected on both sides of the footrest section, the cushion section and the backrest section to ensure the reliability of the connection, so that the left and right sides of the seat fabric are subjected to balanced elastic force.

[0010] Preferably, a card slot is provided on the chair frame corresponding to the elastic band, the card slot is adapted to be connected with a card connector, and the elastic band is connected to the card connector.

[0011] The elastic band and the chair frame are connected via a snap-fit ​​piece, which is snap-fitted into a slot on the chair frame during installation, so the assembly is convenient and the connection is reliable.

[0012] Preferably, the slot and the connector are both in the shape of long strips, the connector is connected to the slot, and the elastic band passes through the slot opening. The outer diameter of the connector is greater than the slot opening width.

[0013] When the card connector is assembled with the card slot, the elastic band is first connected to the card connector, and then the card connector is directly inserted into the card slot, so that the elastic band passes through the card slot opening, and the card connector is directly engaged with the card slot. Since the outer diameter of the card connector is larger than the width of the card slot opening, the card connector can be reliably engaged in the card slot without being separated from the card slot opening.

[0014] In another solution, the clamping member is in a rectangular frame structure, one end of the clamping member is clamped in the clamping slot, and the other end of the clamping member is connected to the elastic band.

[0015] One end of the clamping piece is clamped in the clamping groove, and the other end is connected to the elastic band. The outer surface of the elastic band will not contact or rub against other parts, thereby extending the service life.

[0016] Preferably, a positioning strip is connected to the clamping member, and two ends of the positioning strip are wound around the clamping member to form a clamping joint, and the clamping joint is clamped in the clamping groove.

[0017] When the card connector is assembled and connected with the card slot, the positioning strip is first connected to the card connector, and then one end of the card connector and the positioning strip are inserted into the card slot together. The card connector formed by winding the two ends of the positioning strip will not be separated from the card slot, and the card connector will not be separated from the card connector after being wound on the card connector, so the card connector and the card slot are reliably connected and will not be separated.

[0018] In a third solution, a sleeve is provided on the elastic belt, and the sleeve is connected to the chair frame sleeve.

[0019] The elastic band is directly connected to the chair frame set through a sleeve arranged thereon, eliminating the need for a card slot and a card connector, thus simplifying the structure and reducing the cost.

[0020] Preferably, the chair frame includes a "human" shaped supporting foot, a seat cushion tube is hinged on the supporting foot, the front of the seat cushion tube is hinged to the footrest tube, the rear of the seat cushion tube is hinged to the backrest tube, the supporting foot is connected to the armrest, the front of the armrest is hinged to the footrest tube, the rear of the armrest is hinged to the backrest tube, and the footrest tube, seat cushion tube, backrest tube and seat cloth are all connected by elastic bands.

[0021] The support foot of the chair frame is connected to the seat tube, and the front and rear sides of the seat tube are connected to the footrest tube and the backrest tube respectively. When sitting, the center of gravity is at the seat tube, and the seat tube is directly connected to the support foot, so the force is stable and reliable. The footrest tube, seat tube, backrest tube and seat fabric are all connected by elastic bands, so that all parts of the human body can feel the elastic force when sitting, which is more comfortable.

[0022] Compared with the prior art, the beneficial effects of the present invention are: (1) the chair frame and seat fabric of the seat structure of the present invention are reliably connected, avoiding the safety hazard caused by connection failure; (2) the elastic belts on the seat are arranged at intervals and have a segmented structure, which is ergonomic when lying flat, improves comfort, and reduces the risk of human falling; (3) the elastic belt and the chair frame are easy to connect and assemble, avoiding the welding process, which is conducive to reducing costs.
