[0026] The utility model is a frame and a seat for a seat. When a person sits on the seat, the person applies force to the support frame. Since the spring providing support for the support frame is located in the front half of the support frame, the support frame is more likely to tilt backward and downward. Moreover, when the person sits on the seat and raises his head slightly backward, the center of gravity of the human body also moves backward, which also causes the support frame to tilt backward and downward, and the head of the person on the support frame naturally tilts up. Especially in the movie-watching scene, after the audience takes their seats, when watching the large screen in front and above, they will unconsciously raise their heads, and the center of gravity of the human body will also move backward. At the same time, the setting of the frame is also conducive to the audience's body tilting backward and downward, so that the audience's head is naturally raised, avoiding neck fatigue during the movie-watching process, thereby improving the audience's movie-watching experience.

[0027] Furthermore, when the audience leaves the seat after watching the movie, the support frame returns to its initial position under the action of the spring. The setting of the spring can also avoid the need for the person in the seat to manually adjust the seat angle in the existing adjustable-angle seats, thereby providing convenience for the person in the seat.

[0028] Furthermore, when a person sits on the seat, he first applies force to the seat frame. Since the seat frame is inclined and the front edge of the seat frame is on the upper front side of the rear edge of the seat frame, after the person sits on the seat, the body naturally tilts backward, and then transfers force to the support frame, and then to the spring, making it easier for the entire frame to tilt backward.

[0038] Figure 1 FIG. 1 is a schematic structural diagram of a frame 100 according to an embodiment of the present invention. Figure 1 As shown, and refer to Figure 2 The embodiment of the utility model provides a frame 100 for a seat 10. The frame 100 includes a base 110, a support frame 120, and at least one vertically arranged spring 130. The support frame 120 is located above the base 110. The at least one spring 130 is arranged between the base 110 and the support frame 120 and is located in the front half of the support frame 120, and the at least one spring 130 is connected to both the base 110 and the support frame 120.

[0039] When a person sits on the chair 10, the person applies force to the support frame 120. Since the spring 130 that provides support for the support frame 120 is located in the front half of the support frame 120, the support frame 120 is more likely to tilt backward and downward. Moreover, when a person sits on the chair and raises his head slightly backward, the center of gravity of the human body also moves backward, which also causes the support frame 120 to tilt backward and downward, and the head of the person on the support frame 120 naturally tilts up. Especially in the movie-watching scene, after the audience takes their seats, when watching the large screen in the front and upper part, they will unconsciously raise their heads, and the center of gravity of the human body will move backward. At the same time, the setting of the frame 100 is also conducive to the audience's body tilting backward and downward, so that the audience's head is naturally raised, avoiding neck fatigue during the movie-watching process, thereby improving the audience's movie-watching experience. Further, when the audience leaves the chair 10 after watching the movie, the support frame 120 returns to its initial position under the action of the spring 130. The provision of the spring 130 can also avoid the existing angle-adjustable seat 10 requiring the person on the seat 10 to manually adjust the angle of the seat 10 , thereby providing convenience for the person on the seat 10 .

[0040] In some embodiments, Figure 1 As shown, when the support frame 120 is a regular rectangle, the front half here refers to the front side of the line connecting the midpoints of the two lateral sides of the support frame 120.

[0041] In some embodiments of the present invention, Figure 1 As shown, there are four springs 130, and the four springs 130 include two spring groups, and each spring group includes two springs 130 spaced apart from each other. The two spring groups are spaced apart on both sides of the support frame 120 in the transverse direction.

[0042] When the support frame 120 is tilted backward by force, the spring 130 at the rear side is subjected to pressure, and the spring 130 at the front side is subjected to tension. The two spring groups arranged on both sides make the support frame 120 more stable, and when the support frame 120 is subjected to external force, it is not easy to shake horizontally to both sides.

[0043] In other embodiments of the present invention, there are two springs 130, and the two springs 130 are arranged at intervals in the middle part of the horizontal direction of the support frame 120 along the front-to-back direction. In other words, the two springs 130 are arranged one in front of the other at the front side of the support frame 120 and are located in the middle position of the horizontal direction of the support frame 120.

[0044] In other embodiments of the present invention, two springs 130 are arranged at intervals on both lateral sides of the support frame 120. The two springs 130 are arranged directly below the support frame 120 and are located on both lateral sides of the support frame 120.

[0045] Of course, in other embodiments of the present invention, there may be only one spring 130 .

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the frame 100 further includes a seat frame 140. The front edge of the seat frame 140 is located at the front upper side of the rear edge of the seat frame 140. The seat frame 140 is located at the upper side of the support frame 120, and the rear edge of the seat frame 140 is connected to the support frame 120.

[0047] When a person sits on the seat 10, a force is first applied to the seat frame 140. Since the seat frame 140 is tilted and the front edge of the seat frame 140 is located on the front upper side of the rear edge of the seat frame 140, after the person sits on the seat 10, the body naturally tilts backward, and then the force is transmitted to the support frame 120, and then to the spring 130, which makes it easier for the support frame 120 to tilt backward.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the seat frame 140 is a planar structure, that is, the seat frame 140 is in a plane. The seat frame 140 can be a square frame structure, which can ensure stability, save materials, and reduce the weight of the seat frame 140.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front edge of the seat frame 140 is located in front of the support frame 120. This arrangement can increase the support of the seat frame 140 to the legs of the person and improve comfort.

[0050] In some embodiments of the present invention, the support frame 120 includes two support frame plates 121 extending forward and backward, and two spring groups are respectively arranged between the base 110 and the two support frame plates 121.

[0051] Further, in some embodiments of the present invention, the support frame plate 121 forms a lateral edge of the support frame 120 . In other words, the spring 130 is located at the lateral edge of the support frame 120 .

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the support frame 120 also includes two backrest fixing frames 122, both of which are in the shape of long strips, and the rear edges of the two backrest fixing frames 122 are located at the rear upper side of the front edges of the backrest fixing frames 122. The front ends of the two backrest fixing frames 122 are respectively connected to the rear ends of the two support frame plates 121. The backrest fixing frames 122 can provide installation and support for the backrest of the seat 10.

[0053] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the base 110 includes a base frame and two fixing plates 111 arranged on the upper side of the base frame. The upper surfaces of the two fixing plates 111 are respectively connected to the lower ends of the two springs 130 of the two spring groups, and the lower surfaces of the two fixing plates 111 are respectively connected to the upper surface of the base frame.

[0054] The spring 130 is stressed. To ensure that the spring 130 is firmly installed with the base 110 and the support frame 120, a welding process can be selected, and the two ends of the spring 130 are preferably fully welded with the base 110 and the support frame 120, that is, the outer circles of the two ends of the spring 130 must be welded. After the spring 130 is welded to the support frame plate 121 and the fixing plate 111, the welding assembly is welded to the base 110, and only the front and rear sides of the fixing plate 111 need to be welded. Obviously, the setting of the fixing plate 111 can reduce the difficulty of welding, ensure the welding quality, and facilitate the arrangement of the process route.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the base frame includes an upper frame 112 and a lower frame 113 disposed below the upper frame 112. The area of ​​the lower frame 113 is larger than the area of ​​the upper frame 112, and also larger than the area of ​​the support frame. The arrangement of the lower frame 113 having an area larger than the area of ​​the upper frame 112 and the support frame makes the base 110 more stable, and does not fall over when a person sits down suddenly with force.

[0056] In some embodiments of the present invention, the upper frame 112 and the lower frame 113 are connected together by the columns 114 , which can increase the height of the base 110 without significantly increasing the weight of the base 110 .

[0057] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the support frame plate 121 and the seat frame 140 can both be made of angle steel.

[0058] In some embodiments of the present invention, the upper frame 112 of the base 110 may be made of angle steel, and the lower frame 113 of the base 110 may be made of a hollow square tube.

[0059] In some embodiments of the present invention, in order to prevent the frame 100 from rusting during use, the frame 100 may be surface treated. For example, the surface of the frame 100 may be painted or electroplated. Preferably, the surface of the frame 100 may be electrophoretically treated, which not only makes the frame 100 beautiful but also increases its service life.

[0060] The present utility model embodiment also provides a seat 10, such as Figure 3 As shown, it includes a frame 100, and the frame 100 is the frame 100 of any of the above embodiments.

[0061] In some embodiments of the present invention, the seat 10 includes a covering member disposed outside the frame 100 of the seat 10. The covering member includes a back cushion 210. The back cushion 210 includes two openings facing each other, and the backrest fixing frame 122 is inserted into the insertion holes.

[0062] When the back cushion 210 needs to be installed, the backrest fixing frame 122 is inserted into the insertion hole. This arrangement facilitates the installation of the back cushion.

[0064] The seat 10 includes a group of mutually engaged buckles and holes 123, which are arranged between the corresponding insertion holes and the backrest fixing frame 122. When the back cushion 210 needs to be installed, the backrest fixing frame 122 is inserted into the insertion hole. During the insertion process, the buckle is inserted into the hole 123, so that the connection between the back cushion 210 and the backrest fixing frame 122 is more tightly secured. Preferably, the seat 10 includes two groups of mutually engaged buckles and holes 123, which are respectively arranged between two corresponding insertion holes and the backrest fixing frame 122. Furthermore, since the backrest fixing frame 122 is tilted, when a person sits on the seat 10 and leans back, it is easier to make the support frame 120 tilt backward.

[0065] In some embodiments of the present invention, the buckle is disposed on the backrest fixing frame 122 , and the clamping hole 123 is disposed on the side wall of the insertion hole.

[0066] In some embodiments of the present invention, Figure 3As shown, the covering component further includes a seat cushion 220 , and the seat cushion 220 is disposed on the seat frame 140 .
