The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.

The application provides a seat.

In some embodiments, as shown in connection with fig. 1, the seat includes a seat cushion 100 with a curved surface and a number of legs. The legs serve to provide support to the curved seat cushion 100 such that the curved seat cushion 100 maintains a predetermined height relative to the ground. In one embodiment, the legs are rod-shaped.

The present application also provides a seat cushion 100 with a curved surface.

In some embodiments, the curved surface cushion 100 is supported by legs. In other embodiments, the curved seat cushion 100 may also be used directly on a floor, sofa, bench, chair, or bed.

In some embodiments, as shown in connection with fig. 1-3, a seat cushion 100 with a curved surface includes: main cushion body 20 and flexible cushion layer 30. The main pad body 20 has a carrying surface 21. The carrying surface 21 comprises a first partition 22 and a second partition 23, and the first partition 22 is used for carrying the thigh root of the user. The second partition 23 is used to carry the buttocks of the user. The second partition 23 is provided with a vent 24 penetrating the main cushion 20. The flexible cushion 30 covers at least the first partition 22. The flexible cushion layer 30 is provided with a plurality of first through flow grooves 31 on the side facing away from the main cushion body 20. One end of the first through-flow groove 31 extends to an edge of the flexible cushion 30 away from the second partition 23, and the other end of the first through-flow groove 31 extends to the second partition 23.

Specifically, when the user uses the seat cushion 100 with the curved surface, the thighs of the user are carried on the first section 22, and the buttocks of the user can be carried on the second section 23 entirely or on both the second section 23 and a part of the first section 22. Since the second partition 23 is provided with the ventilation opening 24 penetrating the main cushion body 20, heat released from the buttocks can be released through the ventilation opening 24, and the stuffiness of the buttocks can be reduced. Because the flexible cushion layer 30 is provided with the first through-flow grooves 31 on the side opposite to the main cushion body 20, the first through-flow grooves 31 are concavely arranged relative to other surfaces of the flexible cushion layer 30, so that a channel for air flow to pass through the lower thigh or the lower hip of a user can be provided, and heat on the thigh or the hip surface can be taken away when the air flow passes through the first through-flow grooves 31. Because the one end of first through-flow groove 31 extends to the edge that flexible bed course 30 kept away from second subregion 23, and the other end extends to second subregion 23, the other end of first through-flow groove 31 can communicate to vent 24, and the both ends of first through-flow groove 31 all can supply air flow business turn over to first through-flow groove 31 has better radiating efficiency, effectively eliminates the stuffy feel of user's thigh root and buttock.

In some embodiments, as shown in connection with fig. 3, the plane of symmetry 200 of the carrier surface 21 intersects the vent 24. The length direction of the vent 24 is parallel to the opposite direction between the first and second sections 22, 23. Specifically, since the curved surface 21 is used to contact the thigh root and hip of the user over a large area and the thighs on both sides of the human body have symmetry, the curved shape on the surface 21 is symmetrical about a symmetry plane 200. When the symmetry plane 200 of the carrying surface 21 intersects with the ventilation opening 24, the position of the ventilation opening 24 can correspond to the lower body of the user when the user uses the seat cushion 100 with the curved surface, so that the problem of the lower body being wet is avoided. As shown in connection with fig. 3, the relative direction between the first partition 22 and the second partition 23 is parallel to arrow F31.

In some embodiments, the vent 24 is disposed on a center line of symmetry of the carrier surface 21; the length of the vent 24 is parallel to the center line of symmetry. Specifically, the projected shape of the carrying surface 21 is symmetrically arranged about the center line of symmetry, thereby enabling the position of the vent 24 to correspond to the lower body of the user. In another embodiment, the center of symmetry coincides with the plane of symmetry 200.

More specifically, when the user's body sits on the support surface 21 in the curved shape of the support surface 21, the user's thigh root is mainly supported by the first section 22, and the buttocks are mainly supported by the second section 23, so that the relative direction of the user's front-rear side is parallel to the relative direction between the first section 22 and the second section 23 at this time. Because the dimension of the vent 24 in the length direction is larger than the dimension of the vent 24 in the width direction, when the length direction of the vent 24 is parallel to the opposite direction between the first partition 22 and the second partition 23, the length direction of the vent 24 is parallel to the concave line of the lower body of the user, so that the shielding of the thigh root or the hip of the user to the vent 24 can be reduced, and the heat dissipation effect of the vent 24 is ensured. As shown in connection with fig. 3, the width direction of the vent 24 is parallel to arrow F32.

In one embodiment, the vent 24 is elliptical with the major axis of the ellipse being parallel to the opposite direction between the first and second sections 22, 23.

In some embodiments, as shown in connection with fig. 1 and 5, the edge regions 25 on either side of the carrier surface 21 are curved in a direction proximate to the flexible cushion 30. Specifically, the bending of the regions 25 of the edges 35 on both sides of the carrier surface 21 causes the side edges 35 of the flexible cushion 30 to be raised to a certain height relative to the middle of the second section 23. When a user sits on the seat cushion 100 with the curved surface, the edge regions 25 on both sides of the carrying surface 21 give the user an inward pressing force, so that the pelvis can be naturally folded, and the effect of preventing the displacement of the pelvis is achieved. Meanwhile, the edge areas 25 on both sides of the carrying surface 21 can normalize the sitting posture of the user, so that the user cannot lean up or pan the leg. In particular, for women of childbearing nature, the seat 100 with curved surfaces may act to adjust the pelvis. In addition, the edge regions 25 at both sides of the carrying surface 21 can support the outer sides of the thighs, and increase the contact area between the thighs and the main pad body 20, thereby reducing the pressure of the thighs and the buttocks and improving the comfort.

In some embodiments, the edge regions 25 on either side of the carrier surface 21 are disposed obliquely with respect to the plane of the vent 24. Specifically, since the inclined direction of the edge area 25 is inward, an inward pressing force can also be given to the user.

In some embodiments, as shown in connection with fig. 2, a number of raised blocks 27 are attached to the side of the main cushion body 20 facing away from the flexible cushion layer 30. A plurality of raised blocks 27 are disposed around the vent 24. Specifically, the bottom surface 28 of the main cushion body 20 faces away from the flexible cushion layer 30. When the seat cushion 100 with the curved surface is placed at an angle in the use state, the bottom surface 28 of the main cushion body 20 is vertically downward. The bump 27 is connected to the bottom surface 28 of the main pad body 20 and protrudes with respect to the bottom surface 28 of the main pad body 20. In some embodiments, the raised blocks 27 separate the seating surface from the bottom surface 28 of the main cushion body 20 and form a second through-flow gap when the curved seat cushion 100 is placed on the seating surface. The air flow passing through the ventilation opening 24 can pass through the second ventilation gap between the bearing surface and the bottom surface 28 of the main cushion body 20, so that the heat dissipation effect of the ventilation opening 24 is further ensured.

In some embodiments, two raised blocks 27 are disposed on both sides of the vent 24 in the width direction of the main cushion 20. In some embodiments, the support surface is a floor, a sofa surface, a stool surface, or a chair surface. In some embodiments, the boss 27 is integrally connected to the main pad body 20. As shown in fig. 3, the width direction of the main pad body 20 is parallel to the arrow F32.

In some embodiments, as shown in connection with fig. 3 and 4, the edge of the flexible cushion 30 adjacent to the second section 23 is provided with a concave notch 32. One portion of the vent 24 is within the confines of the indent 32 and another portion is outside the confines of the indent 32. Specifically, since the flexible cushion 30 has a certain thickness after compression, the surface of the flexible cushion 30 is convexly disposed with respect to the carrier surface 21. Assuming that the edge of the flexible cushion 30 adjacent to the second section 23 is an inner edge 33 and the edge of the flexible cushion 30 remote from the second section 23 is an outer edge 34, the portion of the user's body beyond the inner edge 33 of the flexible cushion 30 has a first through-flow gap with the second section 23. Since another portion of the vent 24 is outside the extent of the concave recess 32, another portion of the vent 24 is on the side of the inner edge 33 of the flexible cushion 30 remote from the first section 22. The first through-flow groove 31 and the ventilation opening 24 can be communicated through the first through-flow gap, so that the stability of communication between the first through-flow groove 31 and the ventilation opening 24 can be ensured. More specifically, the other end of the first through-flow groove 31 extends to the inner edge 33 of the flexible mat 30.

In some embodiments, the flexible mat 30 is overlaid to the second section 23, and the inner edge 33 of the flexible mat 30 may be within the confines of the second section 23. In other embodiments, it is also possible that the inner edge 33 of the flexible mat 30 coincides with the edge of the second section 23. Further, when the user uses the seat cushion 100 with a curved surface, the edge of the flexible cushion 30 corresponding to the left or right side of the user is the side edge 35. In some embodiments, one end of the first through-flow channel 31 extends to an outer edge 34 or side edge 35 of the flexible mat 30.

In some embodiments, as shown in connection with fig. 1 and 4, the seat cushion 100 with curved surfaces further includes a rear support 40 connected to the main cushion 20 and a backrest 50 connected to the rear support 40. The rear supporter 40 serves to maintain the backrest 50 at a predetermined angle and position with respect to the main pad 20. Specifically, when the seat cushion 100 with the curved surface is placed at an angle in the use state, the height range of the backrest body 50 is larger than that of the main cushion body 20, and the backrest body 50 serves to provide support to the back of the user. More specifically, the backrest body 50 is used to provide support to the rear waist of the user to provide a load bearing effect to the upper body of the user.

Specifically, the back support body 50 can be provided with a reliable supporting effect for the upper body of the user in the case that the back support body 40 maintains the predetermined angle and position of the back support body 50 with respect to the main cushion body 20. In some embodiments, when the seat cushion 100 with the curved surface is placed at an angle in the use state, the front surface of the seatback body 50 is close to the main cushion body 20 in the horizontal direction. At least a portion of the front surface of the backrest body 50 is inclined upward so as to provide support to the back of the user. Further, when the seat cushion 100 with the curved surface is placed at an angle of a use state, at least a portion of the rear support body 40 is disposed away from the main cushion body 20 along the horizontal direction with respect to the backrest body 50, so as to prevent the rear support body 40 from interfering with the buttocks of the user and prevent the fit between the backrest body 50 and the rear waist of the user from being affected. In some embodiments, the main cushion 20, the rear support 40, and the backrest 50 are integrally injection molded from a high-toughness plastic material.

In some embodiments, as shown in connection with fig. 1 and 4, the width of the rear support 40 is not less than 60% of the width of the main cushion 20. The middle part of the rear support body 40 is provided with a ventilation opening 41. Specifically, since it is necessary to secure the contact area of the main cushion body 20 or the backrest body 50 with the user's body, the width of the main cushion body 20 or the backrest body 50 is substantially fixed. Since the width of the rear support 40 is not less than 60% of the width of the main cushion 20, the rear support 40 and the main cushion 20, or the rear support 40 and the backrest 50 have a larger connection range in the width direction, so that the connection strength between the rear support 40 and the main cushion 20, or the connection strength between the rear support 40 and the backrest 50 can be ensured, which is beneficial to ensuring the angular stability of the backrest 50 relative to the main cushion 20. As shown in connection with fig. 3, the width direction of the rear supporter 40 is parallel to the arrow F32.

Further, in the case that the width of the rear supporter 40 is large, the relative area of the rear supporter 40 and the back of the user is large, but the ventilation opening 41 is provided in the middle of the rear supporter 40, so that the influence of the rear supporter 40 on the heat dissipation of the back of the user can be avoided. More specifically, the middle portion of the rear supporter 40 may be understood as a portion near the midpoint of the rear supporter 40 in the width direction.

In some embodiments, as shown in fig. 1 and 4, a plurality of ribs 42 are integrally connected to a surface of the rear support 40, which is close to the main cushion 20, and the plurality of ribs 42 are distributed along the width direction of the rear support 40, so that the structural strength of the rear support 40 can be improved, and the structural stability of the backrest 50 relative to the main cushion 20 can be improved. In one embodiment, the ventilation openings 41 are provided between the ribs 42 in the width direction of the rear support 40.

In some embodiments, as shown in connection with fig. 1, 4, and 5, the intermediate portion 26 of the first partition 22 is in the form of a ridge. The height of the protuberance and the width of the protuberance of the intermediate portion 26 of the first section 22 increase in a direction away from the posterior branch 40. Specifically, the middle portion 26 of the first section 22 is positioned between the user's thighs when the user uses the seat cushion 100 with the curved surface. Because the height and width of the ridge of the middle portion 26 of the first sub-area 22 increases in a direction away from the rear supporter 40, the middle portion 26 of the first sub-area 22 can generate a horizontal force component on the inner side of the user's thigh, which can prevent the user's thigh or buttocks from sliding in a direction away from the backrest 50, so that the supporting force of the backrest 50 on the user can be balanced, and the upper body of the user can maintain a relatively vertical angle. Referring to fig. 3, the height direction of the ridge faces outward perpendicular to the plane of the drawing sheet, and the width direction of the ridge is parallel to the arrow F32.

In some embodiments, as shown in fig. 1 and 3, the side of the flexible cushion 30 facing away from the main cushion body 20 is distributed with second through-flow grooves 36. The second flow-through slot 36 is positioned and shaped to correspond to the intermediate portion 26 of the first section 22. Specifically, the second through-flow grooves 36 are arranged at positions of the flexible cushion 30 corresponding to the middle part 26 of the first partition 22, and the second through-flow grooves 36 are arranged in a recessed manner relative to other surfaces of the flexible cushion 30, so that the circulation effect of the air flow above the middle part 26 of the first partition 22 can be ensured. The intermediate portion 26 of the first partition 22 is raised to increase the bonding area between the first partition 22 and the user's thigh, and the provision of the second ventilation groove 36 can prevent heat dissipation from affecting the inner side of the user's thigh due to the increase in bonding area.

In some embodiments, the ends of the second flow-through slot 36 extend to the edges of the flexible mat 30, respectively, to allow air flow to freely enter and exit the second flow-through slot 36. More specifically, the second through-flow grooves 36 each extend at both ends to the outer edge 34 of the flexible mat 30. In other embodiments, the second through-flow slots 36 communicate to predetermined holes that extend through both the flexible mat 30 and the main mat 20.

In some embodiments, the second flow-through slot 36 is a-shaped with the small end facing the posterior branch 40. In other embodiments, the second flow-through slot 36 is V-shaped with the small end facing the aft support 40.

In some embodiments, as shown in connection with fig. 5 and 6, the curved seat cushion 100 further includes a plurality of magnetic members 60. The magnetic member 60 is disposed between the main mat body 20 and the flexible mat layer 30. Specifically, the magnetic member 60 has magnetism, and since the use of the magnetic member 60 includes, but is not limited to, physical therapy stimulation of acupoints of a human body, improvement of blood circulation, reduction of fatigue of a body, promotion of energy recovery, improvement of sub-health state of a human body, and elimination of tension, positive effects on health of a user can be exerted by providing the magnetic member 60 between the main mat body 20 and the flexible mat layer 30. In some embodiments, the magnetic member 60 is a magnet.

In some embodiments, as shown in fig. 5 and 6, the main pad 20 is provided with a plurality of grooves 29 in the first partition 22 of the carrying surface 21, the magnetic member 60 is accommodated in the grooves 29, and after the magnetic member 60 is accommodated in the grooves 29, the surface of the magnetic member 60 corresponding to the opening of the grooves 29 is substantially flush with the surface of the peripheral first partition 22. Thereby avoiding the surface of magnetic element 60 from protruding relative to carrier surface 21 and preventing magnetic element 60 from causing localized bulging of flexible mat 30.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
