Technical Field
[0001] This utility model relates to the field of automotive seat technology, and in particular to a structure for covering the center armrest of a rear seat. Background Technology
[0002] In the automotive manufacturing industry, the design of rear seats not only concerns passenger comfort but also has a significant impact on the overall aesthetics and safety of the vehicle. Rear seatbacks typically consist of individually foldable four-quarter and six-quarter seatbacks. The center armrest, as an important component for enhancing the rear passenger experience, is usually located on the frame of the six-quarter seatback and adjacent to it.
[0003] Traditional center armrest installation structures typically involve welding two armrest mounting brackets, one on the left and one on the right, to the three-quarter seat frame. The bottom ends of the armrest box are rotatably connected to these two brackets via pivots. The armrest mounting bracket closest to the edge of the three-quarter seat frame (i.e., the side closest to the four-quarter seat) is usually concealed, recessed into the side of the armrest box. The armrest box has a recessed groove for this bracket, with space provided to allow the armrest box to rotate forward relative to the bracket. The bracket also has a stop point and an open-bottomed plastic protective shell around its outer edge. A limiting shaft extends outward from the recessed groove. When the armrest box is in the stowed position, the limiting shaft is outside the plastic protective shell. When the armrest box rotates forward from the stowed position to the designed position, the limiting shaft rotates into the plastic protective shell and abuts against the stop point in a clockwise direction, thus restricting the rotation position of the armrest box.
[0004] However, the traditional rear seat center armrest cover structure has significant drawbacks, such as... Figure 1 As shown, when the armrest box is in the folded position, due to the small coverage area of the plastic protective shell, there is a partially uncovered area in the recess. This means that the limiting shaft cannot be consistently covered by the plastic protective shell during the armrest box's rotation. This design flaw not only affects the overall aesthetics and consistency of the car seat, but more importantly, the uncovered limiting shaft may pose a safety hazard to passengers while the vehicle is in motion. For example, passengers may accidentally touch the exposed limiting shaft, resulting in injury; or in an emergency, the exposed limiting shaft may cause secondary injury to the passenger. Utility Model Content
[0005] In view of the problems existing in the prior art, the present invention aims to provide a rear seat center armrest covering structure, which extends the outer side of the plastic protective shell to cover the entire groove, effectively solving the aesthetic and safety problems of car seats.
[0006] To achieve the above objectives, this utility model proposes a rear seat center armrest concealment structure, including an armrest box and a three-quarter backrest frame. Two armrest mounting brackets are welded to the three-quarter backrest frame on the left and right sides. The bottom ends of both sides of the armrest box are rotatably connected to the two armrest mounting brackets via pivots. The armrest mounting bracket near the edge of the three-quarter backrest frame is concealed, recessed into the side of the armrest box. The armrest box has a recessed groove for the armrest mounting bracket to recess into, and the groove provides clearance to allow the armrest box to flip forward relative to the mounting bracket. The armrest mounting bracket near the middle of the three-quarter backrest frame is located outside the armrest box, preventing it from interfering with the armrest box when it flips. The interference is caused by a limiting stop on the armrest mounting bracket near the edge of the three-quarter backrest frame. The armrest mounting bracket is fitted with a plastic protective shell with an open bottom along its outline. The recessed groove has a limiting shaft extending outward. When the armrest box is in the storage position, the limiting shaft is outside the plastic protective shell. The inner side of the plastic protective shell has clearance grooves for the limiting shaft to rotate into and for the rotating shaft to pass through. When the armrest box is flipped forward from the storage position to the design position, the limiting shaft can rotate into the plastic protective shell and abut against the limiting stop in a clockwise direction. The outer side of the plastic protective shell extends in all directions to completely cover the recessed groove, so that the limiting shaft can always be covered during the flipping of the armrest box.
[0007] In the above solution: the plastic protective shell completely covers the sink trough, that is, the outer dimensions of the plastic protective shell are perfectly matched with the dimensions of the sink trough, and it will not protrude beyond the sink trough.
[0008] In the above solution: the outer side of the plastic protective shell is flush with the surface of the armrest box, which helps to ensure the consistency of the appearance of the seat back.
[0009] In the above solution: the armrest mounting bracket near the edge of the three-quarter backrest frame has a perforation hole, and the upper edge of the perforation hole has an inwardly protruding arc-shaped protrusion to form a limiting stop. The armrest mounting bracket in the area below the perforation hole arches outward to avoid the passage of the limiting shaft. That is, the upper and lower areas of the perforation hole are offset to the left and right to facilitate the passage of the limiting shaft.
[0010] In the above scheme: the outer side of the plastic protective shell extends in all directions and bends inward to form a flange, which can better wrap and cover the sink and help increase the structural strength of its edge.
[0011] In the above design, the armrest mounting bracket near the edge of the three-quarter backrest frame is arranged diagonally downwards from back to front, thus forming an angled space with the three-quarter backrest frame. This avoids interference with the bottom of the armrest box when it is flipped forward, allowing the armrest box to flip into place. This design helps prevent interference between the bottom of the armrest box and the bottom of the corresponding armrest mounting bracket.
[0012] The beneficial effects of this utility model are as follows: 1. The armrest mounting bracket is equipped with a limiting stop point, and the recessed groove is equipped with an outwardly extending limiting shaft. When the armrest box is flipped forward from the storage position to the design position, the limiting shaft can rotate into the plastic protective shell and abut against the limiting stop point in a clockwise direction, effectively limiting the flipping position of the armrest box, preventing it from over-flipping, and ensuring the safety and stability of use. 2. The outer edge of the armrest mounting bracket is fitted with a plastic protective shell with an open bottom. On the one hand, it can play a certain protective role for the armrest mounting bracket, preventing it from being damaged by external collisions, wear and other damages; on the other hand, the outer side of the plastic protective shell extends in all directions to completely cover the recessed groove, making the overall appearance cleaner and more beautiful, avoiding the exposure of the recessed groove and limiting shaft and other structures, which affects the visual effect, and plays an effective concealing role. It can always cover the limiting shaft during the flipping process of the armrest box, eliminating safety hazards. Moreover, only the outer side of the plastic protective shell extends, and its internal structure remains unchanged, so it will not interfere with the rotation of the armrest box.

[0020] like Figure 2 As shown in Figure 7, a rear seat center armrest cover structure mainly consists of an armrest box 1 and a six-part backrest frame 2, with two armrest mounting brackets 3 welded to the left and right sides of the six-part backrest frame 2.
[0021] The bottom ends of the armrest box 1 are rotatably connected to two armrest mounting brackets 3 via pivots 9. The armrest mounting bracket 3 near the edge of the three-quarter backrest frame 2 is concealed, recessed into the side of the armrest box 1. The armrest box 1 has a recess 4 for the armrest mounting bracket 3 to sink into, with space reserved in the recess 4 to allow the armrest box 1 to flip forward relative to the armrest mounting bracket 3. The armrest mounting bracket 3 near the middle of the three-quarter backrest frame 2 is located outside the armrest box 1, and will not interfere with it when the armrest box 1 flips.
[0022] A limiting stop 7 is provided on the armrest mounting bracket 3 near the edge of the three-quarter backrest frame 2, and a plastic protective shell 5 with an open bottom is fitted around the outer contour of the armrest mounting bracket 3. A limiting shaft 6 extending outward is provided in the recess 4. When the armrest box 1 is in the storage position, the limiting shaft 6 is located outside the plastic protective shell 5. The inner side of the plastic protective shell 5 is provided with clearance grooves 51 for the limiting shaft 6 to rotate into and the rotating shaft 9 to pass through. When the armrest box 1 is flipped forward from the storage position to the design position, the limiting shaft 6 can rotate into the plastic protective shell 5 and abut against the limiting stop 7 in a clockwise direction.
[0023] The outer surface of the plastic protective shell 5 extends in all directions to completely cover the sink 4, thus ensuring that the limiting shaft 6 is always covered during the rotation of the armrest box 1. Only the outer surface of the plastic protective shell 5 extends; its internal structure remains unchanged and will not interfere with the rotation of the armrest box 1.
[0024] Ideally, the plastic protective shell 5 should completely cover the sink 4, meaning that the outer dimensions of the plastic protective shell 5 should perfectly match the dimensions of the sink 4 and not protrude beyond the sink 4.
[0025] Ideally, the outer side of the plastic protective shell 5 should be flush with the surface of the armrest box 1 to ensure a consistent appearance of the seat back.
[0026] Ideally, the armrest mounting bracket 3 near the edge of the six-quarter backrest frame 2 should have a perforation 8. The upper edge of the perforation 8 should have an inwardly protruding arc-shaped protrusion to form a limiting stop 7. The armrest mounting bracket 3 below the perforation 8 should arch outward to avoid the passage of the limiting shaft 6. That is, the upper and lower areas of the perforation 8 should be offset to the left and right to facilitate the passage of the limiting shaft 6.
[0027] Ideally, the outer side of the plastic protective shell 5 extends in all directions and bends inward to form a flange, which can better cover and conceal the sink 4 and help increase the structural strength of its edges.
[0028] Ideally, the armrest mounting bracket 3, located near the edge of the three-quarter backrest frame 2, is arranged diagonally downwards from back to front, thus forming an angled space with the three-quarter backrest frame 2. This allows the armrest box 1 to avoid interference with its bottom when it flips forward, ensuring that the armrest box 1 can flip into place. This design helps prevent interference between the bottom of the armrest box 1 and the bottom of the corresponding armrest mounting bracket 3.
