Description

Technical Field

[0001] This application relates to a sitz bath, a sitz cushion assembly, and a seat. Background Technology

[0002] Seating products, taking car seats as an example, include seat cushion components that provide a seat basin to support the weight of the occupant and provide mounting positions for foam, padding, and other functional components.

[0003] However, the existing solutions for seat basin and cushion components have poor versatility, especially the inability to match the seat basin with front crossbeams of different sizes. This means that when replacing the front crossbeam with a different size, a different size seat basin needs to be replaced, resulting in high costs. Furthermore, the existing solutions for seat basin and cushion components also have problems such as complex structure, inconvenient assembly, and high cost.

[0004] In view of the above, the inventors of this application propose a sitz bath, a cushion assembly, and a seat to solve at least one or a combination of the above technical problems. Utility Model Content

[0005] The purpose of this application is to provide a sitz bath.

[0006] Another object of this application is to provide a seat cushion assembly.

[0007] Another objective of this application is to provide a seat.

[0008] A seat cushion assembly according to a first aspect of this application includes: a seat cushion support including a front crossbeam extending along its width; a seat basin connected to the front crossbeam via a mounting portion; the mounting portion including a first groove disposed in the seat basin and an insert; the first groove and the insert together defining an accommodating space for the front crossbeam; the mounting portion being configurable as a first mounting structure and a second mounting structure; wherein the first mounting structure is configured such that the front crossbeam contacts the first groove and the insert; the second mounting structure is configured such that the front crossbeam is disposed in the accommodating space via a first pad and a second pad, the first pad filling between the first groove and the front crossbeam, and the second pad filling between the insert and the front crossbeam.

[0009] The seat cushion assembly described above, through the configuration of a first mounting structure and a second mounting structure of the mounting part, allows the same mounting part to match front crossbeams of different sizes, thereby improving versatility. For front crossbeams with relatively large sizes, the first mounting structure is used, where the front crossbeam directly contacts the first groove and the insert, thus fully utilizing the accommodating space between the first groove and the insert. For front crossbeams with relatively small sizes, the second mounting structure is used, where a first pad fills the space between the first groove and the front crossbeam, and a second pad fills the space between the insert and the front crossbeam, thus fixing the front crossbeam. Different thicknesses of the first and second pads can be selected according to the specific size of the front crossbeam, making it easy to implement and cost-effective. Furthermore, the design of using the first and second pads to fill from both sides of the front crossbeam allows the same seat basin to be used even when changing to different sizes of front crossbeams, saving costs.

[0010] In one or more embodiments of the seat cushion assembly, the seat basin is integrally formed and includes a front portion and an elastic support portion; the front portion is provided with the mounting portion; the elastic support portion is provided with an elastically deformable support surface.

[0011] The elastic support part can function similarly to the seat cushion suspension spring. By configuring the seat as a single piece that includes the front and the elastic support part, it can replace the component structure of the seat cushion suspension spring, reduce the number of parts and processing molds, simplify assembly operations, and save costs and time.

[0012] In one or more embodiments of the cushion assembly, the elastic support portion has a wavy support surface.

[0013] Using a corrugated support surface can increase deformability and improve support capacity. It can also adapt to external forces by expanding or contracting the local corrugations, and allow the material to extend in multiple directions, including the direction of the corrugations, thereby better distributing the load, improving reliability and extending service life.

[0014] In one or more embodiments of the seat cushion assembly, the mounting portion is configured such that: the first groove has a protrusion, and the first pad correspondingly has a recess, the protrusion contacting the recess to define the position of the first pad; and / or, the insert has a tenon, and the second pad correspondingly has a tenon, the tenon being inserted into the tenon to define the position of the second pad.

[0015] In one or more embodiments of the cushion assembly, the seat basin is a plastic component.

[0016] In one or more embodiments of the seat cushion assembly, it is configured such that: the front crossbeam is a round tube; and / or, the seat cushion support further includes a rear crossbeam extending in the width direction on the rear side, the rear crossbeam being a round tube; and / or, the first groove and the insert are connected by a first snap-fit ​​structure; and / or, the first groove and the first pad are connected by a second resilient snap-fit ​​structure.

[0017] In one or more embodiments of the seat cushion assembly, the mounting portion is further configured with a third mounting structure; the third mounting structure is configured such that the front crossbeam is indirectly disposed in the receiving space provided by the first groove and the insert via one of the first pad and the second pad.

[0018] In one or more embodiments of the seat cushion assembly, the seat cushion support further includes side supports distributed on both sides in the width direction, and a rear crossbeam extending in the width direction at the rear, wherein the front crossbeam and the rear crossbeam are respectively fixed between the side supports on both sides; the seat basin is provided with a second groove corresponding to the rear crossbeam, the second groove accommodating the rear crossbeam; the seat basin is provided with a side portion corresponding to the side supports, the side portion protruding relative to the front portion and the elastic support portion, and the side portion covering the side supports; wherein the first groove has a downward opening, and the second groove has a rearward opening.

[0019] A sitz bath according to a second aspect of this application is configured as a sitz bath in the cushion assembly described in the first aspect.

[0020] A seat according to a third aspect of this application is configured with the cushion assembly described in the first aspect. Attached Figure Description

[0031] It is understood that the seat basin, seat cushion assembly and seat provided in this application are particularly suitable for automobiles, but can also be applied to other applicable occasions, such as rail trains, ships, aircraft, or fixed places, such as meeting rooms, auditoriums, cinemas, etc., as long as the seat can use the seat basin and seat cushion assembly disclosed in the embodiments of this application, and are not limited thereto.

[0032] like Figures 1 to 3 The seat cushion assembly 10 shown includes: a seat cushion support 20 and a seat basin 100; wherein, the seat cushion support 20 (also called the seat cushion frame) includes a section located on the front side of the seat cushion assembly 10 along the width direction ( Figure 1A front crossbeam 21 (perpendicular to the plane of the paper), for example, is a circular tube; a basin 100 is connected to the front crossbeam 21 via a mounting part 110; wherein, the mounting part 110 includes a first groove 111 provided on the front side of the basin 100, and also includes a plurality of inserts 112; the first groove 111 accommodates the front crossbeam 21 and is provided with a plurality of insertion holes 119 that match the plurality of inserts 112; the inserts 112 are inserted into the insertion holes 119, so that the first groove 111 and the inserts 112 together define the accommodating space of the front crossbeam 21, so that the basin 100 is mounted and fixed on the front crossbeam 21; as shown in the figure, the inserts 112 can be configured to penetrate the two side walls of the first groove 111, thereby forming a closed accommodating space to prevent the basin 100 from detaching from the front crossbeam 21; the mounting part 110 is provided with a first mounting structure and a second mounting structure; as Figure 2 As shown, the first mounting structure is adapted to the front crossbeam 21 with a relatively large cross-sectional dimension, and is configured such that the front crossbeam 21 directly contacts the first groove 111 and the insert 112; as Figure 3 As shown, the second mounting structure is adapted to the relatively small front crossbeam 21. The front crossbeam 21 is indirectly disposed in the receiving space formed by the first groove 111 and the insert 112 through the first pad 113 and the second pad 114. The first pad 113 fills between the first groove 111 and the front crossbeam 21, and the second pad 114 fills between the insert 112 and the front crossbeam 21. The dimensions of the first pad 113 and the second pad 114 can be specifically determined according to the front crossbeam 21.

[0033] The seat cushion assembly 10 described above, through the configuration of a first mounting structure and a second mounting structure of the mounting part 110, allows the same mounting part 110 to match front crossbeams 21 with different cross-sectional sizes, thereby improving versatility. For matching relatively large front crossbeams 21 (e.g., round tubes with relatively large diameters), the first mounting structure is used, where the front crossbeam 21 directly contacts the first groove 111 and the insert 112, thus fully utilizing the accommodating space between the first groove 111 and the insert 112. For matching relatively small front crossbeams 21 (e.g., round tubes with relatively small diameters), the second mounting structure is used, where a first pad 113 fills the space between the first groove 111 and the front crossbeam 21, and a second pad 114 fills the space between the insert 112 and the front crossbeam 21, fixing the front crossbeam 21 in position and allowing it to be positioned according to the front crossbeam. The specific dimensions of the front crossbeam 21 are selected by using a first pad 113 and a second pad 114 of different thicknesses, so that the same seat basin 100 can still be used when changing the front crossbeam 21 of different sizes and specifications, which is easy to implement and has a low cost. In addition, the design of filling from both sides with the first pad 113 and the second pad 114 is conducive to adjusting the height of the front side of the seat basin 100. For example, in some cases, the seat cushion support 20 and the seat basin 100 are roughly fixed, and the center position of the front crossbeam 21 (e.g., a round tube) is relatively fixed. When replacing the front crossbeam 21 with a different tube diameter, if the front crossbeam 21 is filled on only one side, it will cause the front side of the seat basin 100 to be unfavorably raised or lowered. At the same time, the use of the first pad 113 and the second pad 114 can keep the seat basin 100 at the same height position, ensuring the comfort and safety of the seat 1.

[0034] like Figure 4 As shown, in one or more embodiments, the basin 100 is integrally formed and includes a front portion 120 and an elastic support portion 130; the front portion 120 is provided with a mounting portion 110; the elastic support portion 130 is provided with an elastically deformable support surface 131 for elastically supporting the load; in other words, at least one area on the support surface 131 of the basin 100 is configured as an elastic support portion 130, which is a structure that is relatively easy to undergo elastic deformation, thereby generating elastic force to support the load, playing a role similar to a seat cushion suspension spring; for example, as shown in the figure, the elastic support portion 130 may have several strip holes 132, which makes it have lower stiffness than other parts of the basin 100, thereby making it easier to undergo elastic deformation under external force and generate elastic force. The elastic support part 130 can function similarly to a seat cushion suspension spring. The seat basin 100 is configured as a single piece including the front part 120 and the elastic support part 130. This can replace the component structure of the seat basin 100 that is attached to the seat cushion suspension spring, reduce the number of parts and processing molds, simplify assembly operations, and save costs and time.

[0035] like Figure 5As shown, in one or more embodiments, the elastic support portion 130 is provided with a wavy support surface 131. The term "wavy" here refers to a continuous, undulating corrugated feature; the corrugations can be semi-circular, square, etc., and are not limited thereto. Using a wavy support surface 131 can increase deformability, enhance support capacity, and adapt to external forces through the expansion or contraction of corrugations in localized areas, as well as allow the material to extend in multiple directions, including the corrugation undulation direction, thereby better distributing loads, improving reliability, and extending service life.

[0036] like Figure 2 , Figure 3 As shown, in one or more embodiments, the mounting portion 110 is configured such that: a first groove 111 has a protrusion 115, and a first pad 113 correspondingly has a recess 116, the protrusion 115 contacting the recess 116 to define the position of the first pad 113; and / or, the insert 112 has a mortise 117, and a second pad 114 correspondingly has a tenon 118, the tenon 118 being inserted into the mortise 117 to define the position of the second pad 114. Specifically, the mounting portion 110 may be configured such that: the first groove 111 opens downward and is generally U-shaped; as Figure 4 As shown, two mounting portions 110 are arranged in the width direction. Two insertion holes 119 are formed by matching two inserts 112 in the same first groove 111. The insertion holes 119 penetrate through the two side walls of the first groove 111. The inserts 112 can be inserted from one side wall and extend out from the other side wall, so that the first groove 111 and the inserts 112 surround the front crossbeam 21, so that the seat 100 is mounted on the front crossbeam 21. The first groove 111 has a protrusion 115 in the middle position. One side of the first pad 113 is shaped like the first groove 111 and has a corresponding protrusion. A recess 116 is provided at position 115, and the other side is shaped like the front crossbeam 21. The protrusion 115 is inserted into the recess 116 to restrict the rotation of the first pad 113. The thickness of the first pad 113 is determined according to the space between the front crossbeam 21 and the first recess 111. The insert 112 is provided with a tenon 117, and the second pad 114 is correspondingly provided with a tenon 118, so that the second pad 114 can be inserted into the insert 112 through the tenon 118 and the tenon 117. The thickness of the second pad 114 is determined according to the space between the front crossbeam 21 and the insert 112. Figure 2 As shown, in the first mounting configuration, the front crossbeam 21 directly abuts against the surfaces of the protrusion 115 and the tenon 117; as Figure 3As shown, in the second mounting structure, the first groove 111 is provided with a first pad 113, the insert 112 is provided with a second pad 114, and the front crossbeam 21 abuts against the first pad 113 and the second pad 114. In some cases, the mounting part 110 also adopts a third mounting structure, in which the front crossbeam 21 is indirectly provided in the accommodating space provided by the first groove 111 and the insert 112 only through one of the first pad 113 and the second pad 114, that is, the front crossbeam 21 abuts between the first pad 113 and the insert 112, or abuts between the second pad 114 and the first groove 111, but is not limited thereto. The mounting part 110 may also be configured with a first snap-fit ​​structure, including a claw and a slot, one of which is located in the first groove 111 and the other in the insert 112. When the insert 112 is inserted into the socket 119, the claw and the slot of the first snap-fit ​​structure cooperate to prevent the insert 112 from falling off unfavorably. The first groove 111 and the first pad 113 may also be fixed by a second snap-fit ​​structure, and are not limited thereto.

[0037] In one or more embodiments, the basin 100 is a plastic part.

[0038] like Figure 1 As shown, in one or more embodiments, the seat cushion assembly 10 is configured such that the front crossbeam 21 is a round tube; and / or, the seat cushion support 20 further includes a rear crossbeam 22 extending in the width direction on the rear side, the rear crossbeam 22 being a round tube.

[0039] like Figure 1 , Figure 4 As shown, in one or more embodiments, the seat support 20 further includes side supports 23 distributed on both sides in the width direction, with the front crossbeam 21 and the rear crossbeam 22 respectively fixed between the two side supports 23; the seat basin 100 is provided with a second groove 141 corresponding to the rear crossbeam 22, the second groove 141 accommodating the rear crossbeam 22; the seat basin 100 is provided with a side portion 150 corresponding to the side supports 23, the side portion 150 protruding relative to the front portion 120 and the elastic support portion 130, thereby providing lateral support to the occupant in the width direction, and the side portion 150 covering the side supports 23; wherein, the first groove 111 has a downward opening, and the second groove 141 has a rearward opening.

[0040] Specifically, the seat cushion assembly 10 can be configured as follows: the seat cushion support 20 includes side supports 23 distributed on both sides in the width direction, and a front crossbeam 21 and a rear crossbeam 22 located on the front and rear sides respectively; the seat basin 100 is a one-piece molded plastic part, and is provided with a front part 120, an elastic support part 130 and a rear part 140 distributed sequentially in the length direction, and two side parts 150 distributed on the left and right sides; wherein, the front part 120 provides space for the mounting part 110 and is provided with a first groove 111 opening downward; the rear part 140 is provided with a second groove 141 opening rearward; the two side parts Each of the 150 components has a downward-facing third groove to cover the side support 23. During assembly, the seat basin 100 is arranged such that the first groove 111, the second groove 141, and the third groove are respectively connected to the front crossbeam 21, the rear crossbeam 22, and the side support 23. The insert 112 is inserted into the insertion hole 119, which can completely fix the seat basin 100 to the seat support 20, making the assembly operation simple. Furthermore, the insert 112 can also be configured to detachably connect to the first groove 111, for example, by using a first snap-fit ​​structure. The entire seat basin 100 can be disassembled simply by removing the insert 112, making the disassembly operation simple.

[0041] like Figure 4 As shown, this application also provides a sitz bath 100, which is configured as the sitz bath 100 of the sitz bath 10 described above as a sitz bath 100 of ...0 described above as a sitz bath 100 of the sitz bath 100 described above as

[0042] like Figure 1 As shown, this application also provides a seat 1, which includes the seat cushion assembly 10 described above.

[0043] In summary, the advanced technical effects of this application include, but are not limited to, at least one of the following:

[0044] By configuring the first and second mounting structures of the mounting section, the same mounting section can be matched with front crossbeams of different sizes, thereby improving versatility. The first mounting structure is used to match relatively large front crossbeams, with the front crossbeam directly contacting the first groove and the insert, thus making full use of the accommodating space between the first groove and the insert. The second mounting structure is used to match relatively small front crossbeams, with the first pad filling the space between the first groove and the front crossbeam, and the second pad filling the space between the insert and the front crossbeam, so that the front crossbeam is fixed. Different thicknesses of the first and second pads can be selected according to the specific size of the front crossbeam, which is easy to implement and has a low cost. Furthermore, the design of using the first and second pads to fill from both sides allows the same seat to be used when changing to different sizes of front crossbeams, thus saving costs.
