Description

Technical Field

[0001] The utility model relates to seat accessories, in particular to a fixing belt for fixing supporting accessories (lumbar support, headrest, etc.) to vehicle or aircraft seats, and a supporting assembly comprising the fixing belt. Background Art

[0002] The applicant first filed a patent application entitled "Lumbar Support and Protection Device" (authorization publication number CN215535369U), and then noticed that the lumbar support and protection device may not be suitable for seats with insufficient seat depth (for example, seats in compact vehicles and seats in the economy class of aircraft). After placing the lumbar support and protection device on the seat, it will occupy the seating space of the occupant.

[0003] In other existing technical solutions, the lumbar support or headrest can be fixed to the seat back with a fixing strap, thereby reducing the space they occupy on the seat surface. For example, in the Chinese utility model patent entitled "Portable Seat Neck and Lumbar Pad" (authorization publication number CN201120863Y), the neck pad and lumbar pad are suspended on the headrest of an aircraft or bus seat via a suspension strap. The suspension strap can be made of flat or round webbing. However, this suspension strap is in the form of a mesh, which is not easy to install or remove quickly and is also difficult to apply to Figure 4 For example, the complex-shaped seat headrest shown in [ ]. Another example is the Chinese utility model patent titled "A Freely Adjustable Back Cushion" (grant publication number CN217804456U), in which the back cushion body is attached to two fixing straps. The four free ends of the two fixing straps are used to secure the seat. The two fixing straps are located on the same side of the back cushion body, and the back cushion body can slide forward and backward along the extension direction of the fixing straps. However, this fixing method is too simple, and the fixing straps are very easy to loosen from the seat.

[0004] It is particularly noteworthy that if these two types of fixing straps become loose in a traffic accident, they can easily become entangled around the body of the seated person (for example, the arms, head and neck). If they are wrapped around the arms, it will affect the seated person's response speed to the traffic accident. If they are wrapped around the head and neck, there is a risk of suffocation for the seated person, therefore posing a safety hazard. Utility Model Content

[0005] In view of the problems existing in the background technology, a first aspect of the present invention provides a fixing belt for fixing a support accessory to a seat, wherein the seat has a backrest and a seat headrest provided on the backrest, a gap being formed between the backrest and the seat headrest, and the fixing belt comprises:

[0006] A flat main body, the width of which exceeds two-thirds of the width of the seat headrest, and having a first end and a second end opposite to each other in the length direction, the first end being provided with an insertion opening, the first end being capable of being wrapped around the seat headrest through the gap, the second end being capable of being inserted into the first end through the insertion opening, so that the first end forms a fastening knot fastened around the seat headrest, and the second end passing through the insertion opening freely hangs down in contact with the backrest;

[0007] a first positioning structure provided on the first end, so that an additional headrest can be coupled to the first positioning structure and provided on the first end; and

[0008] A second positioning structure is provided on the second end so that an additional lumbar support can be combined with the second positioning structure and provided on the second end.

[0009] In some embodiments of the present invention, when the first end is wrapped around the seat headrest, the insertion opening is located in the gap formed between the backrest and the seat headrest, and the second end is inserted with the first end in the gap to form a fastening knot.

[0010] In some embodiments of the present invention, the fixing belt for fixing the support accessory to the seat includes: at least one interlaced strap provided on the first end along the width direction of the main body, and the interlaced opening is formed between the interlaced strap and the first end.

[0011] In some embodiments of the present invention, the fixing belt for fixing the supporting accessory to the seat includes: at least one through cut directly formed on the first end along the width direction of the main body, and the through cut becomes the insertion opening.

[0012] In some embodiments of the present invention, a gap is formed between the backrest and the seat surface, and the inserted second end can be inserted into the gap and clamped in both directions by the backrest and the seat surface so that the second end can be vertically attached to the backrest.

[0013] In some embodiments of the present invention, the first positioning structure and the second positioning structure are a combination of one or more positioning straps, Velcro, and snap fasteners.

[0014] Another aspect of the present invention provides a support assembly, comprising:

[0015] Any of the above-mentioned fixing straps;

[0016] an additional headrest capable of being coupled to the first positioning structure and provided on the first end of the fixing strap; and / or

[0017] An additional waist support capable of being combined with the second positioning structure and arranged on the second end of the fixing belt

[0018] The utility model has the following beneficial effects:

[0019] First, the fixing belt provided in the present application is fixed to the seat by wrapping around the seat headrest. Especially for seats with insufficient seat depth in compact vehicles or economy class aircraft, it does not take up additional seating space for the occupant and is easy to install and remove.

[0020] Secondly, seat headrests come in a variety of shapes, and some with additional features (such as adjustable angles) have complex structures. Conventional rope-shaped fixing straps simply hang from the headrest, making them unsuitable for headrests with complex shapes and structures. Such fixing methods are also prone to loosening. The fixing strap of the present application, with its main body wrapped around the headrest to form a secure knot, offers a more reliable fixing method that is less likely to loosen.

[0021] Furthermore, the fixing belt has a flat body and its width exceeds two-thirds of the seat headrest. It is not easy to get entangled around the body of the seat occupant (for example, arms, head and neck) in a traffic accident, even if it is loosened, thereby avoiding the risk of affecting the seat occupant's response speed to traffic accidents or causing the seat occupant to suffocate, as in the prior art.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figure 1-6 As shown, this embodiment provides a fixing belt 200 for fixing a support accessory to a seat 100. The seat 100 has a backrest 110 and a seat headrest 120 arranged on the backrest 110. A gap A is formed between the backrest 110 and the seat headrest 120. The fixing belt 200 includes a flat main body 210, a first positioning structure 220, and a second positioning structure 230.

[0039] The width of the main body 210 exceeds two-thirds of the width of the seat headrest 120, and it has a first end 211 and a second end 212 in the longitudinal direction. The first end 211 is provided with an insertion opening 211a. The first end 211 can be wrapped around the seat headrest 120 through the gap A. The second end 212 can be inserted into the first end 211 through the insertion opening 211a, so that the first end 211 forms a fastening knot that is tightly wrapped around the seat headrest 120. The second end 212 passes through the insertion opening 211a and hangs freely against the backrest 110. The first positioning structure 220 is provided on the first end 211, so that the additional headrest 300 can be combined with the first positioning structure 220 and arranged on the first end 211 (see Figure 7-10 The second positioning structure 230 is provided on the second end 212 so that the additional lumbar support 400 can be combined with the second positioning structure 230 and provided on the second end 212 to provide installation positioning (refer to Figure 10 ).

[0040] In this embodiment, the flat body 210 is made of soft artificial leather, so that the first end 211 can form a fastening knot that is fastened around the seat headrest 120, and the second end 212 passing through the insertion hole 211a can better fit the backrest 110 and hang freely.

[0041] In other embodiments, the flat body 210 may also be made of soft leather or canvas.

[0042] The first positioning structure 220 and the second positioning structure 230 are a combination of one or more of positioning straps, Velcro, and snap fasteners.

[0043] In this embodiment, the first positioning structure 220 is selected from three positioning straps (see in particular the first positioning straps 220 and the first positioning straps 220) provided on the front side of the first end 211 of the main body 210. Figure 1 and Figure 6 ), wherein two positioning straps are provided along the length of the main body 210, and one positioning strap is provided along the width of the main body 210. The two ends of the positioning straps are fixedly connected to the main body 210, so that a gap is formed between the middle portion of the positioning straps and the main body 210. The positioning straps can also be made of soft artificial leather. The additional headrest 300 can be equipped with a common backpack buckle or elastic cord. The backpack buckle or elastic cord can be passed through the corresponding positioning strap to install the additional headrest 300 on the first end 211 of the main body 210.

[0044] In this embodiment, the second positioning structure 230 is a Velcro fastener (see in particular the Velcro fastener) provided on the reverse side of the second end 212 of the main body 210. Figure 2 and Figure 3), the Velcro extends along the length direction of the main body 210, and the additional lumbar support 400 can be provided with a matching Velcro, so that the additional lumbar support 400 is mounted on the second end 212 of the main body 210 in an adhesive manner.

[0045] In other embodiments, the first positioning structure 220 may be formed of a larger or smaller number of positioning straps, Velcro, or snap fasteners. Similarly, the second positioning structure 230 may be formed of a positioning strap or snap fasteners. The installation principle is the same as above.

[0046] Those skilled in the art will appreciate that, first, the fixing strap 200 provided herein is secured to the seat 100 by wrapping around the seat headrest 120. This avoids taking up extra seating space for the occupant, and is easy to install and remove, particularly for seats with insufficient seat depth, such as those in compact vehicles or in the economy class cabin of an aircraft. Secondly, seat headrests 120 come in a variety of shapes, and some with additional features (such as adjustable angles) have more complex structures. The existing rope-like fixing straps simply hang from the seat headrest 120, making them unsuitable for seat headrests 120 with complex shapes and structures. Such fixing methods are also prone to loosening. The fixing strap 200 provided herein, wherein the main body 210 wraps around the seat headrest 120 to form a secure knot, is more reliable and less likely to loosen. Furthermore, the fixing belt 200 has a flat main body 210 and its width exceeds two-thirds of the seat headrest 120. It is not easy to get entangled around the body of the seat occupant (for example, arms, head and neck) in a traffic accident, even if it is loosened, thereby avoiding the risk of affecting the seat occupant's response speed to traffic accidents or causing the seat occupant to suffocate, as in the prior art.

[0047] Reference Figure 3 and 4 As shown, further, when the first end 211 is wrapped around the seat headrest 120, the insertion opening 211a is located in the gap A formed between the backrest 110 and the seat headrest 120, and the second end 212 is inserted with the first end 211 in the gap A to form a fastening joint.

[0048] Those skilled in the art will appreciate that inserting the first end 211 and the second end 212 in the gap A to form a fastening knot saves space, is more aesthetically pleasing, and does not affect the seating experience.

[0049] Furthermore, the fixing belt 200 includes at least one insertion belt 213 fixed to the first end 211 along the width direction of the main body 210 , and the insertion opening 211 a is formed between the insertion belt 213 and the first end 211 .

[0050] In this embodiment, one insertion strap 213 is provided, and both ends of the insertion strap 213 are fixedly connected to the first end 211 , so that the insertion opening 211 a is formed between the middle portion of the insertion strap 213 and the first end 211 .

[0051] In other embodiments, a plurality of interlaced straps 213 may be provided in parallel, so that the fixing straps can be adapted to seat headrests 120 of various shapes and sizes.

[0052] Alternatively, the fixing belt 200 includes at least one through cut formed directly on the first end 211 along the width direction of the main body 210 , and the through cut becomes the insertion opening 211 a .

[0053] In this embodiment, one through cut is provided, and the width of the second end 212 needs to be slightly smaller than the width of the through cut, so as to ensure that the second end 212 can pass through the through cut.

[0054] In other embodiments, a plurality of through cuts may be provided in parallel, so that the fixing strap can be adapted to seat headrests 120 of various shapes and sizes.

[0055] Furthermore, a gap B is formed between the backrest 110 and the seat surface 130 , and the inserted second end 212 can be inserted into the gap B and clamped in both directions by the backrest 110 and the seat surface 130 so that the second end 212 can be vertically attached to the backrest 110 .

[0056] Those skilled in the art will appreciate that when the second end 212 hangs freely, its relative position to the backrest 110 can be easily adjusted. Once the adjustment is complete, users with good sitting posture can simply install the additional lumbar support 400 on the second end 212. However, for users with poor sitting posture, their twisting movements can cause the second end 212 (and the additional lumbar support 400) to shift. Therefore, the second end 212 is designed to be sufficiently long to fit into the gap B and be clamped by the backrest 110 and the seat surface 130 in both directions, keeping the second end 212 in a taut state. Installing the additional lumbar support 400 can prevent this shift.

[0057] Reference Figure 7-10 As shown, the present invention also provides a support assembly, including any one of the aforementioned fixing belts 200, an additional headrest 300 that can be combined with the first positioning structure 220 and is set on the first end 211 of the fixing belt 200; and / or an additional lumbar support 400 that can be combined with the second positioning structure 230 and is set on the first end 212 of the fixing belt 200.

[0058] In this embodiment, the first positioning structure 220 is a positioning belt, and the back side of the additional headrest 300 is provided with an elastic rope or backpack buckle that can pass through the positioning belt. The additional headrest 300 can adjust the length of the elastic rope or backpack buckle. Figure 7-9 The additional headrest 300 can be shaped like the neck cushion in the patent application for "Portable Seat Neck and Lumbar Pad" (licensing number CN201120863Y), or any other conventional shape.

[0059] In this embodiment, the second positioning structure 230 is made of Velcro, and the back of the additional lumbar support 400 is also provided with Velcro. The additional lumbar support 400 can be attached at different heights to accommodate users of different heights. The specific shape of the additional lumbar support 400 can be similar to the lumbar cushion described in the patent application for "Portable Seat Neck and Lumbar Cushion" (Granted Publication No. CN201120863Y), the second component described in the patent application for "Lumbar Support and Protection Device" (Granted Publication No. CN215535369U), or other conventional shapes.

[0060] Those skilled in the art will appreciate that the support assembly includes the aforementioned fixing belt 200 and therefore also includes all the technical effects produced by the aforementioned fixing belt 200. In addition, the positions of the additional headrest 300 and the additional lumbar support 400 on the support assembly are adjustable, thereby being suitable for occupants of different heights.
