Description

Technical Field

[0001] The utility model relates to the technical field of seat design, in particular to a novel seat base. Background Art

[0002] At present, in order to improve the comfort, a serpentine spring is usually installed on the seat to provide elastic support for the human body, that is, a serpentine spring with a flat shape as a whole (such as Figure 5 The two ends of the serpentine spring are connected to the two sides of the seat, and the seat cushion is installed on the top of the serpentine spring to complete the assembly of the seat. However, this structure of the serpentine spring still has certain defects in actual use. On the one hand, since the serpentine spring is flat as a whole, the middle part of the serpentine spring is subjected to downward force in actual use, which easily causes excessive force on the connection points at both ends to cause stretching deformation, affecting the service life of the serpentine spring; on the other hand, since the middle part of the spring moves downward during use, the center area of ​​the serpentine spring is lower than the connection points at both ends, and the connection points at both ends are in a fixed state, which will cause the user to come into contact with the fixing clips at both ends of the serpentine spring (such as the seat frame) when sitting, affecting the comfort when sitting. Utility Model Content

[0003] The utility model provides a novel seat base to solve the problems of short service life and poor comfort of the serpentine spring caused by the existing seat base proposed in the above background technology.

[0004] The technical solution of the utility model is achieved in this way:

[0005] A novel seat base includes a base frame, to which a plurality of equally spaced serpentine springs are connected, wherein the serpentine springs have a horizontal support portion, and downwardly bent vertical support portions are connected to both ends of the horizontal support portion, and the ends of the vertical support portions are connected to horizontal connecting portions that are horizontally folded outward.

[0006] Preferably, a plurality of connection buckles for connecting with the horizontal connection parts are provided at both ends of the base frame, and the connection buckles are folded in a direction away from the serpentine spring.

[0007] Preferably, the base frame includes two mutually parallel frames, the horizontal connecting portion of the serpentine spring is connected to the frames, the two frames are connected by a connecting frame, and the middle portion of the connecting frame extends downwards of the two frames.

[0008] Preferably, it also includes a fixing rope for connecting the serpentine spring, and the serpentine spring and the fixing rope are connected via a fixing ring.

[0009] Preferably, there are three fixing ropes, which are respectively arranged near the two ends and the middle of the serpentine spring.

[0010] Preferably, the number of the serpentine springs is five.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0012] The utility model has a simple design structure. On the basis of a traditional flat serpentine spring, downward-bending vertical support parts and outward-bending horizontal connecting parts are arranged at both ends of the serpentine spring, which can improve the structural strength of the two ends of the serpentine spring and avoid deformation problems caused by excessive tensile force. In addition, since the overall thickness of the serpentine spring is increased, the two ends of the serpentine spring can produce a certain deformation when in use, avoiding the problem of poor comfort caused by direct contact between the body and the frame of the base frame.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As shown in the figure, a new type of seat base includes a base frame 1, and a plurality of serpentine springs 2 are connected to the base frame 1 and arranged at equal intervals. The serpentine spring 2 has a horizontal support portion 201, and downwardly bent vertical support portions 202 are connected to both ends of the horizontal support portion 201, and the ends of the vertical support portions 202 are connected to horizontal connecting portions 203 that are horizontally folded outward. That is, the serpentine spring 2 has a frame-like structure as a whole, which can improve the structural strength at both ends when in use, avoid excessive deformation caused by excessive tensile force, and extend its service life; and because the overall height of the serpentine spring 2 is increased, it can avoid direct hard contact between the human body and the base frame 1 when sitting, which is conducive to improving comfort.

[0023] The base frame 1 includes two parallel frames 102 , the horizontal connecting portion 203 of the serpentine spring 2 is connected to the frames 102 , the two frames 102 are connected via a connecting frame 101 , and the middle of the connecting frame 101 extends downwards from the two frames 102 .

[0024] Specifically, a plurality of connecting buckles 103 for connecting to the horizontal connecting part 203 are provided at both ends of the base frame 1, and the connecting buckles 103 are folded in a direction away from the serpentine spring 2, that is, both ends of the serpentine spring 2 are connected to the connecting buckles 103, so that the serpentine spring 2 can be quickly installed.

[0025] Specifically, it also includes a fixing rope 3 for connecting the serpentine spring 2, and the serpentine spring 2 and the fixing rope 3 are connected by a fixing ring 4. In this example, there are three fixing ropes 3, which are respectively arranged near the two ends and the middle of the serpentine spring 2. More specifically, there are five serpentine springs 2. The fixing rope 3 can be used to connect all the serpentine springs 2, so that when in use, all the serpentine springs 2 can be raised and lowered synchronously, making the force more uniform and the structure more stable, avoiding the situation where some serpentine springs 2 are subjected to force while other serpentine springs 2 are not subjected to force.
