Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to a novel widening folding armrest. Background Technology

[0002] Currently, many popular car models on the market feature a large six-seat layout. The goal is to maintain both the width of the aisle between the second-row seats and the width of the seats themselves. Given the limited overall width of the vehicle, an armrest that can widen or narrow according to actual needs has become a pressing need in the industry. However, existing armrests typically lack this functionality. Therefore, it is necessary to design an armrest that can widen or narrow according to actual usage. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a new type of widening folding handrail. When passengers are riding, the handrail can be opened and folded horizontally to widen it, becoming a wide handrail for comfortable arm support. When the handrail is not in use, it can be folded horizontally to narrow it. After the handrail is folded away, a larger space is left in the middle aisle, which is convenient for passengers in the second and third rows to pass through.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel widening folding armrest includes an armrest body, a side-flipping assembly, a locking mechanism, and an unlocking mechanism. The armrest body is mounted on a seat frame and can rotate longitudinally relative to the seat frame. A pivot is provided within the armrest body along its length, and the pivot is rotatably connected to the armrest body. The side-flipping assembly is located on the outer side of the armrest body and is fixedly connected to the pivot. The side-flipping assembly can fold laterally by 90° relative to the armrest body. The locking mechanism locks the pivot when the side-flipping assembly is unfolded by folding laterally by 90°. The unlocking mechanism is located at the front end of the armrest body and unlocks the pivot, allowing the side-flipping assembly to fold laterally.

[0006] As a preferred embodiment of this utility model, the side-tilting assembly includes a side-tilting cover assembly, a side-tilting foam, a side-tilting inner plate, a cover plate, and a side-tilting metal bracket; wherein, the side-tilting cover assembly covers the side-tilting foam, the side-tilting foam is assembled with the side-tilting inner plate by a foam injection molding process, the side-tilting inner plate is snapped onto the cover plate, the cover plate is connected to the side-tilting metal bracket, and the side-tilting metal bracket is welded to the rotating shaft.

[0007] As a preferred embodiment of this utility model, the inner side of the side-flipping assembly is provided with a permanent magnet, and the side-flipping assembly is connected to the upper cover of the handrail body by magnetic attraction.

[0008] As a preferred embodiment of this utility model, a buffer rubber block is provided on the metal frame of the handrail body at a position adjacent to the side-tilting metal bracket.

[0009] As a preferred embodiment of the present invention, the locking mechanism includes a first bracket installed and fixed on the metal frame of the handrail body, the rotating shaft passing through the first bracket and having a wear-resistant bushing between it and the first bracket, a ratchet that rotates synchronously with the rotating shaft being installed on the rotating shaft, and a pawl being installed on the first bracket, the ratchet and the pawl cooperating to achieve locking.

[0010] As a preferred embodiment of this utility model, the unlocking mechanism is located near the locking mechanism and includes a second bracket, a button, and a locking hook that are mounted and fixed on the metal frame of the handrail body. The second bracket has a through hole at a position opposite to the pivot. The button is connected to the handrail body via a small pivot and a first torsion spring. The button can be lifted relative to the handrail body and automatically reset under the action of the first torsion spring. One end of the button, extending into the handrail body, engages with the locking hook. The locking hook is connected to the second bracket via a stepped bolt and a second torsion spring. The locking hook can rotate relative to the second bracket along the stepped bolt and reset under the action of the second torsion spring. The locking hook is used to drive the pawl of the locking mechanism to rotate, thereby unlocking the handrail.

[0011] Advantages and beneficial effects of this utility model:

[0012] (1) This utility model breaks through the traditional car handrail that can only be folded, and innovatively provides a handrail that can be widened and folded, giving full play to the function of the sample. When using the handrail, it can be folded horizontally to widen the handrail, providing sufficient area for support, making the arm support more comfortable and improving comfort. When not in use, the handrail can be folded sideways and vertically (folded horizontally to narrow the handrail, and then folded up), leaving enough space in the aisle of the car for the passage of passengers in the second and third rows.

[0013] (2) The handrail of this utility model has a damping feel when it is folded horizontally, which makes it feel better and has a locking function to ensure the reliability of the wide handrail formed after folding.

[0014] (3) Compared with the previous manual folding armrests, electric folding armrests and aviation seat armrests, which could not be widened horizontally and could only be folded vertically, this application achieves both vertical folding and horizontal folding and widening, providing more usage scenarios and usage needs in a breakthrough of the previous structural forms.
