[0012] Figure 1 This is a front view of a preferred embodiment of the present invention, in which a strap is used as a seat connection device; Figure 2 This is a schematic diagram showing the unfolded rear side of the corresponding embodiment; Figure 3 A schematic diagram showing the side-mounted configuration of the system of the present invention on a seat is provided. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the accompanying drawings are schematic simplified diagrams and do not constitute a limitation on the present invention. like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a complete form of a modular and reconfigurable seat headrest fixing system; See Figure 1 The front view of the system shows a rectangular fabric base, which can be divided into three main areas from top to bottom: a headrest fixing module 1, a lumbar fixing module 2, and a seat cushion extension module 3. On the front of the headrest fixing module 1, there is a first Velcro area 13 for attaching the headrest. The strap 14 extends from the first fixing point 111 on the back... Figure 2 Starting from the front, it passes through the second shuttle ring 112 and the third shuttle ring 113 in sequence. The free end of the strap 14 passes through the automatic buckle 15, which is fixed at the fourth fixing point 114. On the front of the lumbar fixing module 2, there is a second Velcro area 22 for attaching the lumbar pillow. The pillow fixing module and the lumbar fixing module are flexibly connected by an elastic band 21. See Figure 2 On the back of the pillow fixing module 1, near the top, there is a first fixing point 111 for sewing the starting end of the fixing strap 14, and a pillow anti-slip pad 12 is sewn thereon. On the bottom area of ​​the back of the cushion extension module 3, a cushion anti-slip pad 33 is sewn thereon. See Figure 3The actual installation and use of this system is as follows: Place the headrest fixing module 1 at the top of the seat back, so that the strap 14 wraps around the headrest rod or behind the backrest, tightens it, and then passes its free end through the automatic locking buckle 15 and locks it, completing the upper fixing. Let the integrated lumbar and seat cushion modules hang down naturally, so that the seat cushion extension module 3 lies flat on the seat cushion. After the user sits down normally, the weight of their buttocks presses the anti-slip pad 33 firmly onto the seat cushion. Figure 3 As shown, users can quickly install personal headrests, lumbar pillows and other multi-functional accessories (headrest 4 is shown as an example in the picture) onto the corresponding pillow or lumbar fixing module through Velcro (13, 22) and put them into use. It should be understood that the above description of the strap device as a seat connection device is merely an example and not a limitation. Those skilled in the art, after reading this specification, will be fully capable of using any other feasible connection device, such as a sleeve type, suspension type, clamp type, adsorption type, magnetic type, adhesive type, or plug-in type, based on the description of "Technical Solution B," to achieve the purpose of fixing the fixing module to the seat. For example, the top of the fabric can be sewn into a sleeve that can be fitted into the seat headrest (sleeve type); or hooks can be added to both sides for hanging on the armrests (suspension type); or strong suction cups can be added to the back for adsorption onto the plastic plate on the side of the seat (adsorption type). The fixing module of this invention provides a universal connection platform. For example... Figure 1 As shown, on the front of the pillow fixing module and the lumbar fixing module, the Velcro area (13, 22) is a preferred embodiment of the "first connecting surface" of the detachable connection system. Correspondingly, the "multi-functional accessories" such as headrests and lumbar supports used by the user should have a matching "second connecting surface" (such as hook-and-loop Velcro). Based on this principle, those skilled in the art can easily replace the Velcro connection with various mechanical connection methods such as hooks, snaps, and zippers, thereby achieving quick installation and replacement of accessories and fixing modules. For example, a dedicated lumbar support can be designed, which connects to the female buckle on the lumbar part of the fixing module via a row of snaps; or a storage bag can be designed, which connects to the fixing module via a zipper. All these variations based on the same inventive concept should be included within the protection scope of this invention.
