Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically to a seating unit, a bed frame having the unit, and a chair. Background Technology

[0002] In the field of seating and reclining furniture technology, products such as chairs and beds are usually equipped with seating units that enhance user comfort. These seating units typically include a support body and a functional sleeve covering it. The support body consists of a seat cushion that supports the buttocks and a backrest that supports the back, forming a basic ergonomic support structure.

[0003] To address the challenges of high temperatures in summer, existing technologies often employ an improved solution involving adding a cooling layer to the functional seating unit. This involves using a cooling layer made of natural cooling materials such as bamboo mats that comes into contact with the body, utilizing the material's thermal conductivity to lower the skin temperature and thus improve the cooling experience during summer use. However, the overall comfort of these seating units still has room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a seating unit that can further enhance user comfort in high-temperature summer environments.

[0005] The overall technical solution of this utility model is as follows:

[0006] The seating unit of this utility model is designed to further improve user comfort in high-temperature environments during summer. It includes: a support body and a sleeve fitted around the outer periphery of the support body;

[0007] The supporting structure is formed by bending: a seat cushion that forms a buttock support structure, and a backrest that forms a back support structure;

[0008] The cover includes: a seat cover that covers the upper part of the seat cushion for contact with the buttocks, and a back cover that covers one side of the backrest for contact with the back.

[0009] Both the seat cushion cover and the backrest cover are provided with a cooling surface layer on the outer surface;

[0010] The upper surface where the seat cushion meets the backrest has an upward-facing air duct, with both ends of the air duct being through-holes.

[0011] Furthermore, the cover has a connecting sleeve portion that connects the seat cushion cover portion and the backrest cover portion. The connecting sleeve portion has a portion that is adapted to be accommodated in the air retention groove. This portion is recessed into the air retention groove and has a groove on the surface of the cover with an upward opening and through at both ends.

[0012] Both the seat cushion and backrest cover are equipped with a cooling layer to create a cooling sensation that comes into direct contact with the buttocks and back, providing a cooler and more comfortable seating experience for occupants. Simultaneously, airflow channels are provided at the junction of the seat cushion and backrest (the part that doesn't directly support the occupant), and the cover is fitted with a groove structure to accommodate these channels. This increases the space for airflow between the seating unit and the outside air, allowing more and better airflow between the occupant and the seating unit when in use. This creates a cooling airflow (especially when using a fan) to cool the areas of the occupant's body that are difficult to cool (the area of ​​the body facing the seating unit while seated), thus providing a more comfortable experience in hot summer conditions.

[0013] The connecting sleeve can be made of any suitable material, such as textiles or cotton. However, when textiles or cotton are used, there is a problem of temperature discontinuity between the cool surface of the seat cushion and the cool surface of the backrest, which can lead to inconsistent temperature sensations when sitting, thus reducing the comfort of the ride.

[0014] Therefore, in some designs, the connecting sleeve is also provided with a cooling layer on the outer surface;

[0015] Furthermore, the cooling layer of the connecting sleeve is configured such that one end is connected to the cooling layer of the seat cushion sleeve, and the other end is connected to the cooling layer of the backrest sleeve.

[0016] Implementation: By providing a cooling layer that connects the cooling layer of the seat cushion cover and the cooling layer of the backrest cover in the connecting sleeve, a larger cooling surface area is formed, reducing areas of temperature discontinuity and providing passengers with a more comfortable riding experience.

[0017] Among them, the cold surface layer is usually made of rattan mat, bamboo mat or straw mat, and its sitting experience is often quite hard.

[0018] In some designs, a cotton layer and / or a mesh layer are provided between the seat cover and the seat cushion.

[0019] As a preferred option, in some designs, an elastic cushioning layer is provided between the seat cover and the seat cushion. By providing a cushioning layer between the seat cover and the seat cushion, a more soothing and elastic support effect can be provided for the buttocks, while the seat cover can also better conform to the curve of the buttocks to deform to a certain extent, thereby bringing a more comfortable riding experience to the passenger.

[0020] Furthermore, in some designs, the cushioning layer has several ventilation holes, which form channels to guide air downwards from the seat cushion cover. By incorporating ventilation holes in the cushioning layer, the breathability of the seating unit can be improved, thereby providing a more comfortable riding experience for passengers.

[0021] In actual use, passengers often repeatedly adjust their sitting posture while using the seating unit (especially when children are active) to relieve muscle and joint pressure by changing their sitting position within a small range. This can lead to excessive deformation of the ventilation holes, causing them to break.

[0022] Based on this, furthermore, in some designs, several buffer holes are provided between two adjacent vent holes;

[0023] The buffer hole is a through hole that runs vertically through the entire structure, and the diameter of the buffer hole is smaller than the diameter of the vent hole.

[0024] By setting several buffer holes, the air permeability is further improved. On the other hand, the stress originally concentrated in the air vents can be dispersed. The air vents and buffer holes can jointly bear the concentrated stress caused by the movement of passengers, reducing the possibility of tearing deformation of the air vents, improving the air permeability stability of the buffer layer during use, and extending its service life.

[0025] In some designs, the sleeve is detachably fitted onto the outer periphery of the support body, and one end of the sleeve is provided with an insertion port for the support body to enter and exit the sleeve.

[0026] The sleeve opening is equipped with a zipper for opening and closing, facilitating easy disassembly, cleaning, or replacement of the sleeve, which tends to accumulate dirt.

[0027] When the sleeve is fitted onto the bent support body, the protrusions formed by the bent support body often cause excessive stretching of the sleeve, resulting in excessive tightness and easy damage.

[0028] Furthermore, the cover has a portion located on the lower surface where the seat cushion meets the backrest, this portion having several outwardly protruding pleats. By providing the pleats, a stretchable space is formed on the cover to accommodate the protruding portion formed by the bending support body, reducing the tightness of the cover installation and making the cover installation more convenient and stable.

[0029] The bed frame includes the seating unit described in any of the above embodiments.

[0030] The seat includes the seating unit described in any of the above embodiments.

[0031] The main beneficial effects of the above technical solution are as follows:

[0032] 1. Cooling layers are provided on both the seat cushion cover and the backrest cover to form a cooling layer that comes into direct contact with the buttocks and back, providing a cooler and more comfortable seating experience for the occupants of the seating unit.

[0033] 2. At the same time, an air duct is provided at the junction of the seat cushion and the backrest, and the cover is adapted to form a groove structure to accommodate the air duct. This increases the space for air convection between the seat unit and the outside air. When the occupant uses the seat unit, more and better outside air can circulate through the area between the occupant and the seat unit, forming a heat dissipation airflow to cool down the occupant's body surface areas that are not easily cooled. This provides a more comfortable user experience for the occupant in high-temperature environments in summer.

[0034] 3. By providing a cooling layer that connects the cooling layer of the seat cushion cover and the cooling layer of the backrest cover in the connecting sleeve, a larger cooling surface area is formed, reducing areas of temperature discontinuity and providing passengers with a more comfortable riding experience.

[0035] 4. By setting a buffer layer between the seat cover and the seat cushion, a more soothing and elastic support effect can be provided for the buttocks, while the seat cover can also better conform to the curve of the buttocks to deform to a certain extent, thus bringing a more comfortable riding experience to the passengers.

[0036] 5. By incorporating ventilation holes in the buffer layer, the breathability of the seating unit can be improved, thereby providing passengers with a more comfortable riding experience.

[0037] 6. By setting several buffer holes, the breathability is further improved. On the other hand, the stress originally concentrated in the air vents can be dispersed. The air vents and buffer holes can jointly bear the concentrated stress caused by the movement of passengers, reducing the possibility of tearing deformation of the air vents, improving the breathability stability of the buffer layer during use, and extending its service life.

[0038] 7. The detachable design of the cover makes it easy to disassemble, clean, or replace the cover that is prone to accumulating dirt.

[0039] 8. By setting up pleats, a stretchable space is formed on the sleeve body to accommodate the protrusions formed by the bending support body, reducing the tightness of the sleeve body during installation, and thus making the sleeve body easier and more stable to install.

[0040] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0046] Figure 5 This is a schematic diagram of the buffer layer structure. Detailed Implementation

[0047] The present invention will be illustrated with specific examples below:

[0048] Example 1:

[0049] A seating unit is a supporting structure placed on a bed or chair for a person to sit on. (See attached image) Figure 1 and attached Figure 2 As shown, it mainly includes: a support body 1 for providing support to passengers, and a sleeve 2 fitted around the support body 1.

[0050] The support body 1 is a board structure made of sponge, silicone or other materials commonly used in seat cushions. One end of it is bent upwards, so that the support body 1 is bent to form: a cushion part 1.1 that constitutes the buttock support structure and a backrest 1.2 that constitutes the back support structure.

[0051] The cover 2 is a textile piece provided based on the support body 1 and fitted around the outer periphery of the support body 1. Based on the arrangement of the seat cushion 1.1 and the backrest 1.2, the cover 2 includes: a seat cushion cover 2.1 covering the seat cushion 1.1 for contact with the buttocks, and a backrest cover 2.2 covering one side of the backrest 1.2 for contact with the back.

[0052] Both the seat cushion cover 2.1 and the backrest cover 2.2 are provided with a cooling layer 2.3 on their outer surfaces. That is, a cooling layer 2.3 is formed on the outer surface of both the seat cushion cover 2.1 and the backrest cover 2.2. The cooling layer 2.3 is a layered structure made of a cooling material or fabric such as rattan, bamboo, or straw mat, and is used to provide a cooling sensation to the passenger in direct contact.

[0053] As attached Figure 1As shown, an upward-opening air vent 13 is formed on the upper surface where the seat cushion 1.1 meets the backrest 1.2. Both ends of the air vent 1.3 are through-holes, so that the air vent 1.3 forms a "V" or "U" shaped groove.

[0054] Furthermore, the sleeve 2 has a connecting sleeve 2.4 that connects the seat cushion sleeve 2.1 and the backrest sleeve 2.2. The connecting sleeve 2.4 has a portion that is adapted to be accommodated in the air retention groove 1.3. This portion is recessed into the air retention groove 1.3 and has a groove on the surface of the sleeve 2 with an upward opening and through at both ends. That is, when the sleeve 2 is fitted onto the outer periphery of the support body 1, the sleeve 2 has a connecting sleeve 2.4 that aligns with the air retention groove 1.3. The connecting sleeve 2.4 is placed in the air retention groove 1.3 and covers the inner wall of the air retention groove 1.3, so that the outer surface of the sleeve 2 also has a groove with an upward opening and through at both ends.

[0055] The connecting sleeve 2.4 may also be provided with a cooling layer 2.3 on its outer surface; one end of the cooling layer 2.3 is connected to the cooling layer 2.3 of the seat cushion sleeve 2.1, and the other end is connected to the cooling layer 2.3 of the backrest sleeve 2.2, so that the cooling layer 2.3 of the connecting sleeve 2.4, the cooling layer 2.3 of the seat cushion sleeve 2.1, and the cooling layer 2.3 of the backrest sleeve 2.2 can all be connected to form a large, uninterrupted cooling area.

[0056] A cotton layer, a mesh layer, or a multi-layer structure formed by stacking cotton and mesh layers can be provided between the seat cover part 2.1 and the seat cushion part 1.1 to optimize the riding experience.

[0057] Or, as attached Figure 3 and attached Figure 4 As shown, an elastic cushioning layer 2.5 is provided between the seat cover portion 2.1 and the seat cushion portion 1.1. The cushioning layer 2.5 is an elastic layered structure formed by weaving, or an elastic layered structure made of silicone or rubber, etc., to provide elastic shock-absorbing support at the bottom of the seat cover portion 2.1.

[0058] The buffer layer 2.5 may also be provided with a number of ventilation holes 2.51. The ventilation holes 2.51 are channels provided in the buffer layer 2.5 and are vertically connected to form a channel for guiding the air at the seat cover part 2.1 downward.

[0059] As attached Figure 5As shown, for some of the vent holes 2.51, several buffer holes 2.52 can also be provided between two adjacent vent holes 2.51. The buffer holes 2.52 are through holes that run vertically through each other, and the diameter of the buffer holes 2.52 is smaller than the diameter of the vent holes 2.51 (for example, the diameter of the buffer holes 2.52 can be about one-fifth to one-third of the diameter of the vent holes 2.51).

[0060] As attached Figure 5 As shown, in this embodiment, a number of buffer holes 2.52 are arranged at intervals along the direction of the line connecting the centers of two adjacent vent holes 2.51 to improve the stability of the overall hole arrangement in the buffer layer 2.5.

[0061] In the above scheme, the sleeve 2 is detachably fitted onto the outer periphery of the support body 1, and one end of the sleeve 2 is provided with an assembly opening 2.6 for the support body 1 to enter and exit the sleeve 2. The assembly opening 2.6 is provided with a zipper 2.7 for opening / closing the assembly opening 2.6. By controlling the zipper 2.7 to open the assembly opening 2.6, the support body 1 can be installed into the sleeve 2, or the support body 1 can be removed from the sleeve 2; after the support body 1 is installed into the sleeve 2, the assembly opening 2.6 can be closed by controlling the zipper 2.7, thus completing the assembly of the seating unit.

[0062] Based on the above-described assembly and disassembly configuration, the sleeve 2 has a portion located on the lower surface of the junction between the seat cushion portion 1.1 and the backrest 1.2, which has several outwardly protruding pleats. When the support body 1 is installed into the sleeve 2, these pleats are adapted to accommodate the portion of the support body 1 located on the lower surface of the junction between the seat cushion portion 1.1 and the backrest 1.2.

[0063] When the seating unit is in use:

[0064] When a passenger sits on the seating unit, their buttocks rest on the seat cushion 1.1 and seat cover 2.1, while their back rests on the backrest 1.2 and backrest cover 2.2. Simultaneously, the area where the buttocks and back meet (the area below the lumbar region) is suspended relative to the air duct 1.3. A significant amount of external air flows through the grooves on the outer surface of the cover 2 between the passenger and the seating unit (especially when used with a fan), providing a cooling airflow to the passenger and thus offering a cooler and more comfortable riding experience in summer.

[0065] Example 2:

[0066] The bed frame includes a bed board for a person to lie down and rest, on which a seating unit as described in any of the embodiments in Example 1 is placed.

[0067] Example 3:
