Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a seat that can be both flipped up and folded down. Background Technology

[0002] A car seat is a seat used while riding in a vehicle, providing drivers and passengers with an easy-to-operate, comfortable, and safe driving and riding position. It should meet the following conditions: the arrangement of seats throughout the vehicle should be reasonable, especially the driver's seat, which must be in the optimal position; the seat's design must conform to human physiological functions, striving for aesthetics while ensuring comfort; the seat must be safe and reliable, possessing sufficient strength, rigidity, and durability, with a compact structure and minimal weight; various adjustment mechanisms designed to meet the comfort needs of drivers and passengers must have reliable locking devices to ensure safety.

[0003] Currently, with the increasing demand for diverse interior space functions, Volkswagen is no longer satisfied with simply expanding the interior space by folding the rear seat backs forward. While folding the rear seat backs forward expands the trunk space, the space in the seating area between the front and rear seats remains difficult to utilize effectively. Therefore, this invention proposes a seat that can both fold upwards and downwards to solve the above problems. Utility Model Content

[0004] This invention provides a seat that can both flip up and fold down, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a seat that can be both flipped up and folded down includes a backrest frame, a seat cushion frame, a seat cushion front support assembly, support point, backrest locking column, backrest lock, backrest lock mounting sheet metal bracket, backrest angle adjuster connecting bracket, seat cushion angle adjuster connecting bracket, angle adjuster, backrest rotation bracket and angle adjuster unlocking handle.

[0006] The backrest frame is provided with a backrest lock mounting sheet metal bracket on one side, and a backrest lock is provided on the backrest lock mounting sheet metal bracket. The backrest lock is connected to the backrest lock column. The backrest lock is connected to the backrest frame through the backrest lock mounting sheet metal bracket. The left and right sides of the backrest frame are also provided with backrest angle adjuster connecting brackets, and an adjuster is provided on the backrest angle adjuster connecting bracket.

[0007] The seat cushion frame has seat cushion angle adjuster connecting brackets on both the left and right sides. The seat cushion angle adjuster connecting brackets connect the angle adjuster. The seat cushion frame and the backrest frame are connected by two oppositely distributed backrest rotating brackets. The bottom side of the seat cushion frame also has an angle adjuster unlocking handle, which is used to unlock the angle adjuster.

[0008] Preferably, when the seat is in the sitting position, the backrest frame is located at the rear end of the seat cushion frame, and the backrest lock is in the locked position and locks the backrest lock column; when the seat cushion frame is in the sitting position, the front support leg assembly of the seat cushion is blocked by the support leg stop and supports the seat cushion frame, and the angle adjuster is in the unlocked position.

[0009] Preferably, when the seat back and cushion need to be folded and lowered synchronously, the backrest lock is unlocked and the backrest frame is pushed forward. At this time, the backrest lock pin disengages from the backrest lock, the backrest frame rotates forward along the rotation axis on the backrest rotating bracket, and drives the bent tube on the cushion frame to move forward through the angle adjuster. The front support leg assembly of the cushion rotates backward under the obstruction of the support leg stop point, controlling the cushion to move forward and lower simultaneously. When the backrest is folded forward to reach the horizontal position, the angle adjuster locks, thus completing the synchronous folding and lowering of the backrest frame and the cushion frame.

[0010] Preferably, when the seat back and cushion need to be unfolded from the folded-down state, the angle adjuster unlocking handle is engaged to unlock the angle adjuster, pushing the backrest frame. The backrest frame rotates backward along the rotation axis on the backrest rotating bracket. The angle adjuster causes the cushion frame to rise, and the front support leg assembly of the cushion rotates downward to unfold until the backrest lock locks the backrest locking column. At this time, the seat back and cushion unfold from the folded-down state back to the sitting state.

[0011] Preferably, when the seat cushion needs to be flipped up separately, the front end of the seat cushion frame is lifted upwards. When the seat cushion is flipped up to a position that is relatively horizontal with the backrest, the angle adjuster automatically locks, locking the seat cushion frame in the flipped-up state. The front support leg assembly of the seat cushion is then manually rotated upwards and folded to the bottom of the seat cushion frame. At this time, the seat cushion is in the flipped-up state.

[0012] Preferably, when it is necessary to restore the seat cushion of the seat in the stand-up position to the sitting position, the angle adjuster unlocking handle is pulled to unlock the angle adjuster, and then the seat cushion frame is flipped down while the front support leg assembly of the seat cushion is reset, at which point the seat cushion returns to the sitting position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The seat used in this utility model can both flip up and fold down. Because its structure is different from traditional seats, it cleverly uses a backrest rotation bracket and an angle adjuster to connect the seat cushion frame and the backrest frame. This allows the seat cushion to fold forward and sink down while the backrest is folded up. However, it is not limited to this single function. The seat cushion can also be flipped up independently. This expands the space and makes full use of the seating space between the front and rear rows, making the use of the interior space more versatile. Attached Figure Description

[0031] This embodiment uses a six-point side seat, which will be described in the following description;

[0032] Please see Figures 1 to 7 This utility model provides a technical solution: a seat that can be both flipped up and folded down, including a backrest frame 1, a seat cushion frame 2, a seat cushion front support leg assembly 3, support leg stops 4, a backrest locking column 5, a backrest lock 6, a backrest lock mounting sheet metal bracket 7, a backrest angle adjuster connecting bracket 8, a seat cushion angle adjuster connecting bracket 9, an angle adjuster 10, a backrest rotation bracket 11, and an angle adjuster unlocking handle 12;

[0033] A backrest frame 1 has a backrest lock mounting sheet metal bracket 7 on one side, a backrest lock 6 on the backrest lock mounting sheet metal bracket 7, a backrest lock 6 connected to a backrest lock post 5, and a backrest lock 6 connected to the backrest frame 1 through the backrest lock mounting sheet metal bracket 7. The backrest frame 1 also has a backrest angle adjuster connecting bracket 8 on the left and right sides, and an angle adjuster 10 on the backrest angle adjuster connecting bracket 8.

[0034] The seat cushion frame 2 is provided with seat cushion angle adjuster connecting brackets 9 on the left and right sides. The seat cushion angle adjuster connecting brackets 9 are connected to the angle adjuster 10. The seat cushion frame 2 and the backrest frame 1 are connected by two oppositely distributed backrest rotating brackets 11. The bottom side of the seat cushion frame 2 is also provided with an angle adjuster unlocking handle 12, which is used to unlock the angle adjuster 10.

[0035] In this embodiment, the backrest lock 6 is provided with an unlocking lever, and the lever has a pull strap. Pulling the pull strap unlocks the backrest lock 6 from the backrest lock post 5; the foot stop 4 is located on the top surface of the vehicle floor.

[0036] When the seat is in the sitting position, the backrest frame 1 is located at the rear end of the seat cushion frame 2. At this time, the backrest lock 6 is in the locked state and locks the backrest lock column 5. When the seat cushion frame 2 is in the sitting position, the front support leg assembly 3 of the seat cushion is blocked by the support leg stop point 4 and supports the seat cushion frame 2. The angle adjuster 10 connects the backrest and seat cushion of the seat through the backrest angle adjuster connecting bracket 8 and the seat cushion angle adjuster connecting bracket 9. The angle adjuster 10 is in the unlocked state.

[0037] When the seat back and seat cushion need to be folded and lowered synchronously, unlock the backrest lock 6 and push the backrest frame 1 forward. At this time, the backrest lock pin 5 disengages from the backrest lock 6. The backrest frame 1 rotates forward along the rotation axis on the backrest rotation bracket 11 and pushes the bent tube on the seat cushion frame 2 through the angle adjuster 10, thereby driving the seat cushion frame 2 to move forward. The seat cushion front support leg assembly 3 rotates backward under the obstruction of the support leg stop point 4, controlling the seat cushion to move forward and lower at the same time. When the backrest is folded forward to reach the horizontal position, the angle adjuster 10 locks. At this time, the synchronous folding and lowering of the backrest frame 1 and the seat cushion frame 2 is completed.

[0038] When the seat back and cushion need to be unfolded from the folded-down state, the angle adjuster unlock handle 12 is pulled to unlock the angle adjuster 10, pushing the backrest frame 1. The backrest frame 1 rotates backward along the rotation axis on the backrest rotation bracket 11. The angle adjuster 10 drives the cushion frame 2 to rise, and the front support leg assembly 3 of the cushion rotates downward to unfold until the backrest lock 6 locks the backrest lock column 5. At this time, the seat back and cushion unfold from the folded-down state back to the sitting state.

[0039] When the seat cushion needs to be flipped up separately, since the seat adjuster 10 is in the unlocked state when seated, the front end of the seat cushion frame 2 is lifted up directly. When the seat cushion is flipped up to a position that is relatively horizontal with the backrest, the seat adjuster 10 automatically locks, locking the seat cushion frame 2 in the flipped-up state. The front support leg assembly 3 of the seat cushion is manually rotated upward and folded to the bottom of the seat cushion frame 2. At this time, the seat cushion is in the flipped-up state separately.

[0040] When it is necessary to restore the seat cushion from its individually flipped-up position to the seated position, the angle adjuster release lever 12 is pulled to unlock the angle adjuster 10, and then the seat cushion frame 2 is flipped down while the front support leg assembly 3 of the seat cushion is reset, at which point the seat cushion returns to the seated position.

[0041] The structure of this utility model is also applicable to four-way side seats, see appendix. Figure 8 and Figure 9 , Figure 8This is a three-dimensional view of the overall structure of this utility model in a quarter-folded, submerged state. Figure 9 This is a three-dimensional view of the overall structure of this utility model when the four-quarter side seat cushion is flipped up; the operating principle of the four-quarter side seat is the same as that of the six-quarter side seat.

[0042] The working principle and usage process of this utility model are as follows: When the seat is in the sitting position, the backrest frame 1 is located at the rear end of the seat cushion frame 2. At this time, the backrest lock 6 is in the locked state and locks the backrest lock column 5. When the seat cushion frame 2 is in the sitting position, the seat cushion front support leg assembly 3 is blocked by the support leg stop point 4 and supports the seat cushion frame 2. The angle adjuster 10 connects the backrest and seat cushion of the seat through the backrest angle adjuster connecting bracket 8 and the seat cushion angle adjuster connecting bracket 9. The angle adjuster 10 is in the unlocked state.

[0043] When the seat back and seat cushion need to be folded and lowered synchronously, unlock the backrest lock 6 and push the backrest frame 1 forward. At this time, the backrest lock pin 5 disengages from the backrest lock 6. The backrest frame 1 rotates forward along the rotation axis on the backrest rotation bracket 11 and pushes the bent tube on the seat cushion frame 2 through the angle adjuster 10, thereby driving the seat cushion frame 2 to move forward. The seat cushion front support leg assembly 3 rotates backward under the obstruction of the support leg stop point 4, controlling the seat cushion to move forward and lower at the same time. When the backrest is folded forward to reach the horizontal position, the angle adjuster 10 locks. At this time, the synchronous folding and lowering of the backrest frame 1 and the seat cushion frame 2 is completed.

[0044] When the seat back and cushion need to be unfolded from the folded-down state, the angle adjuster unlock handle 12 is pulled to unlock the angle adjuster 10, pushing the backrest frame 1. The backrest frame 1 rotates backward along the rotation axis on the backrest rotation bracket 11. The angle adjuster 10 drives the cushion frame 2 to rise, and the front support leg assembly 3 of the cushion rotates downward to unfold until the backrest lock 6 locks the backrest lock column 5. At this time, the seat back and cushion unfold from the folded-down state back to the sitting state.

[0045] When the seat cushion needs to be flipped up separately, since the seat adjuster 10 is in the unlocked state when seated, the front end of the seat cushion frame 2 is lifted up directly. When the seat cushion is flipped up to a position that is relatively horizontal with the backrest, the seat adjuster 10 automatically locks, locking the seat cushion frame 2 in the flipped-up state. The front support leg assembly 3 of the seat cushion is manually rotated upward and folded to the bottom of the seat cushion frame 2. At this time, the seat cushion is in the flipped-up state separately.

[0046] When it is necessary to restore the seat cushion from its individually flipped-up position to the seated position, the angle adjuster release lever 12 is pulled to unlock the angle adjuster 10, and then the seat cushion frame 2 is flipped down while the front support leg assembly 3 of the seat cushion is reset, at which point the seat cushion returns to the seated position.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
