The structure and adjustment method of the seat side support apparatus 100-1 will be described with reference to fig. 2, 3a to 3c and fig. 4.
Referring to fig. 2, the seat side supporting apparatus 100-1 includes a supporting plate 1, two swing links 2, a swing link seat 3, a first locking mechanism and a second locking mechanism, and the swing links 2 include a first connection portion 21, a second connection portion 22 and a third connection portion 23. The first connecting portion 21 and the second connecting portion 22 are integrally disposed along the seat height direction h, and the third connecting portion 23 is integrally disposed at an angle to the seat height direction h. The first connection portion 21, the third connection portion 23, and the second connection portion 22 are sequentially disposed along the seat height direction h, forming a Z-shaped structure. The first connecting portion 21 is connected with the support plate 1 and can rotate relative to the support plate 1, and the first locking mechanism is used for fixing the first connecting portion 21 and the support plate 1. The second connecting part 22 is connected with the swing rod seat 3 and can rotate relative to the swing rod seat 3, and the second locking mechanism is used for fixing the second connecting part 22 and the swing rod seat 3. The swing rod 2 of the embodiment is a Z-shaped round rod, and has simple structure and easy manufacture. In other embodiments of the present utility model, the swing link 2 may have other shapes, and only three portions forming a Z-shaped structure are required, so that the distance between the support plate 1 and the swing link seat 3 along the width direction w of the seat is adjustable.
The first locking mechanism comprises a first pressing plate 41 and two first locking bolts 42, in order to realize the stable connection between the first locking bolts 42 and the supporting plate 1, the supporting plate 1 is internally provided with a metal insert 11, the structure of the metal insert 11 is shown in fig. 4, and a plurality of through holes are formed, so that the injection molding material and the metal insert 11 can be combined more firmly during injection molding. The first connecting portion 21 is sandwiched between the first pressing plate 41 and the support plate 1, and the first locking bolt 42 is sequentially screwed with the first pressing plate 41 and the metal insert 11.

The fourth locking mechanism comprises two fourth locking bolts 81 and corresponding locking blocks 82, the sliding rail 7 is of a C-shaped structure, the locking blocks 82 in the sliding rail 7 are limited along the seat height direction h, the fourth locking bolts 81 penetrate through the swing rod seat 3 along the seat height direction h and are in threaded connection with the corresponding locking blocks 82, limiting steps 33 are arranged on the swing rod seat 3 corresponding to the fourth locking bolts 51, and the heads of the fourth locking bolts 81 are arranged on the limiting steps 33. The slide rail 7 is fixed on the wheelchair seat board 200 through the fixing component 71, the fourth locking bolt 81 is unscrewed, the swing rod seat 3 is grasped to exert force, and the position of the support plate 1 in the seat depth direction d can be adjusted. The position of the fixing assembly 71 relative to the slide rail 7 in the seat depth direction d is adjustable to accommodate different wheelchair seat plates 200. Referring to fig. 1, the seat board 200 is adjustable in size along the depth direction d of the seat, a plurality of mounting holes 201 for fixing the front fixing components 71 of the sliding rail 7 are provided on the seat board 200, and after the seat board 200 is adjusted to different lengths, the front fixing components 71 of the sliding rail 7 are locked to different mounting holes 201.
In other embodiments of the present utility model, if the sliding rail structure is not provided, a plurality of hole sites may be provided on the seat plate instead, and the position of the support plate 1 in the seat depth direction d may be changed by locking the swing rod seat 3 at different hole sites.
Comparing fig. 3b and 3a, the seat side supporting device in the state shown in fig. 3b can be obtained by adjusting the seat side supporting device in the state shown in fig. 3a in the direction of the arrow in fig. 3 a. Comparing fig. 3c and 3b, the seat side supporting device in the state shown in fig. 3c can be obtained by adjusting the seat side supporting device in the state shown in fig. 3b in the direction of the arrow in fig. 3 b.
