[0028] In related technologies, the rear seats are usually folded forward as a whole to expand the space and make room for a bed to be laid out in the back. When the rear seats fold forward, the seat cushions start to tilt from a roughly horizontal position. When the rear seats are folded to their limit, the seat cushions are held against the floor wall inside the cabin and cannot fold forward any further. At this point, the seat cushions are roughly in an upright position, which still affects the overall space for laying out a bed.

[0029] Please refer to the following for details. Figures 1-8 This application provides a vehicle seat.

[0030] To facilitate understanding, the directions in this utility model are first defined as follows: The directions of up, down, front, back, left, and right involved in this utility model refer to the orientation of a car in the vehicle's O-XYZ coordinate system. The origin O coincides with the center of mass of the vehicle. The front end refers to the X direction parallel to the ground pointing forward, the rear end refers to the X direction parallel to the ground pointing backward, the left side refers to the Y direction parallel to the ground pointing to the driver's left, the right side refers to the Y direction parallel to the ground pointing to the driver's right, the upper end refers to the Z direction passing through point O pointing upward, and the lower end refers to the Z direction passing through point O pointing downward. The XY plane is a horizontal plane.

[0031] Please refer to Figures 1-3 The vehicle seat includes a seat cushion 100, a backrest, and a hinge bracket 300. The seat cushion 100 supports the buttocks, and the backrest, connected to the rear end of the seat cushion 100, supports the back. The hinge bracket 300 connects to the vehicle's cabin. The hinge bracket 300 can be directly or indirectly connected to the cabin. In some embodiments, the vehicle seat includes a fixed support leg 200, which is fixed to the cabin. The hinge bracket 300 is connected to the fixed support leg 200 and indirectly connected to the cabin via the fixed support leg 200.

[0032] Please refer to Figure 1 The hinge bracket 300 has a first hinge position 300a and a second hinge position 300b, which are respectively located at both ends of the hinge bracket 300. The seat cushion 100 is hinged to the hinge bracket 300 through the first hinge position 300a, that is, the seat cushion 100 can rotate relative to the hinge bracket 300 around the first hinge position 300a. The hinge bracket 300 can rotate around the second hinge position 300b.

[0033] The seat cushion 100 is configured to be able to flip relative to the hinge bracket 300 in a first direction via a first hinge point 300a, and the seat cushion 100 and the hinge bracket 300 can also be flipped together relative to the cabin in the first direction via a second hinge point 300b. The first direction is the direction from the rear to the front of the vehicle. It can be understood that by causing the seat cushion 100 and the hinge bracket 300 to flip together around the second hinge point 300b in the first direction, after flipping to their limit angle, the seat cushion 100 can continue to flip around the first hinge point 300a in the first direction, thereby enabling a larger flip angle and increasing the space behind the seat.

[0034] It is understood that the hinge bracket 300 has a first initial posture and a first folded posture. The hinge bracket 300 in the first initial posture can be flipped to the first folded posture in a first direction. The seat cushion 100 has a second initial posture and a second folded posture relative to the hinge bracket 300. The seat cushion 100 in the second initial posture can be flipped to the second folded posture in the first direction. Specifically, if the hinge bracket 300 in the first initial posture flips to the first folded posture, and the seat cushion 100 and the hinge bracket 300 remain relatively stationary during the flipping process, then the seat cushion 100 remains in the second initial posture. When the hinge bracket 300 is in the first folded state and the seat cushion 100 is in the second folded posture, the seat cushion 100 is folded to its maximum angle to maximize the rear space.

[0035] In some embodiments, the seat cushion 100 is configured such that after the hinge bracket 300 flips relative to the cabin to a first folded position, it then flips relative to the hinge bracket 300 from a second initial position to a second folded position. That is, the time it takes for the hinge bracket 300 to rotate around the second hinge position 300b precedes the time it takes for the seat cushion 100 to rotate around the first hinge position 300a. This makes the motion trajectory relatively predictable, thereby improving the controllability and stability of the operation.

[0036] In some specific embodiments, an elastic element such as a torsion spring or a damping element is provided at the first hinge position 300a. The elastic element provides resistance so that the time it takes for the seat cushion 100 to rotate around the first hinge position 300a is slower than the time it takes for the seat cushion 100 and the hinge bracket 300 as a whole to rotate around the second hinge position 300b.

[0037] In other embodiments, the hinge bracket 300 is configured such that after the seat cushion 100 is flipped to a second folded position relative to the hinge bracket 300, it then flips from a first initial position to a first folded position. That is, the seat cushion 100 rotates around the first hinge position 300a before the hinge bracket 300 rotates around the second hinge position 300b.

[0038] In some embodiments, the time during which the seat cushion 100 rotates around the first hinge position 300a partially or completely overlaps with the time during which the hinge bracket 300 rotates around the second hinge position 300b. That is, the seat cushion 100 and the hinge bracket 300 rotate synchronously for part or all of the time periods.

[0039] Please refer to Figure 1 and Figure 4 In some embodiments, the cushion 100 includes a cushion body 110 and a connector 120. The cushion body 110 is used to support the weight of the human body. The connector 120 connects to the cushion body 110 and forms a first connection position 100a at the connection between the two. The connector 120 is also hinged to the hinge bracket 300 through the first hinge position 300a.

[0040] The backrest is connected to the seat cushion body 110, and the first connection point 100a is located at the end of the seat cushion body 110 away from the backrest. Specifically, in the vehicle's cabin, the backrest is located at the rear end of the seat cushion body 110, and the first connection point 100a is located at the front end of the seat cushion body 110.

[0041] In some specific embodiments, the seat cushion body 110 has a frame, and the connector 120 is connected to the frame within the seat cushion body 110. The connector 120 includes a beam 121 and a hinge ear 122. The beam 121 is connected to the frame within the seat cushion body 110 and extends along the Y direction. The hinge ear 122 is connected to the beam 121 and is hinged to the hinge bracket 300. Two sets of hinge ears 122 are spaced apart along the extension direction of the beam 121.

[0042] Please refer to Figure 4 In some embodiments, the dimension between the first connecting position 100a and the first hinge position 300a is smaller than the dimension between the first hinge position 300a and the second hinge position 300b. Thus, as the seat cushion 100 and the hinge bracket 300 are flipped forward to their limit angle around the second hinge position 300b, the seat cushion 100 can move forward a greater distance.

[0043] In other embodiments, please refer to Figure 7 When the hinge bracket 300 rotates to its limit angle around the second hinge position 300b, that is, when the hinge bracket is in the first folded posture, the seat cushion 100 has already pressed against the bottom wall of the cabin. At this time, if the seat cushion 100 continues to fold forward to... Figure 8 As shown, the seat cushion 100 will overcome gravity and rotate around the first hinge position 300a. The first hinge position 300a will rise. In the above scenario, making the size between the first connection position 100a and the first hinge position 300a relatively small can reduce the resistance of the seat cushion 100 rotating around the first hinge position 300a, thereby reducing the difficulty of flipping.

[0044] Please refer to Figure 4 and Figure 6 In some embodiments, when the seat cushion 100 is in the second initial posture, the height of the first hinge position 300a is higher than that of the second hinge position 300b. When the seat cushion 100 is in the second folded posture, the first hinge position 300a is located in front of the second hinge position 300b. At this time, the height of the first hinge position 300a and the height of the second hinge position 300b are not limited; they can be higher than the second hinge position 300b, lower than the second hinge position 300b, or flush with the second hinge position 300b.

[0045] Please refer to Figure 1 In some embodiments, the vehicle seat further includes a first limiting member and a second limiting member 400. The first limiting member is connected to the hinge bracket 300, and the second limiting member 400 is connected to the seat cushion. When the seat cushion 100 is in a second folded posture, the second limiting member 400 abuts against the first limiting member, at which point the seat cushion 100 is limited and cannot continue to flip in the first direction. That is, the first limiting member and the second limiting member 400 cooperate to limit the extreme angle of the seat cushion 100's flip relative to the hinge bracket 300. The connection method between the second limiting member 400 and the seat cushion 100 is not limited; for example, they can be fixedly connected or integrally formed. In some specific embodiments, the second limiting member 400 is an edge extension of the connector 120, and the two are integrally formed.

[0046] Please refer to Figure 1 In some embodiments, the vehicle seat also includes a fixed support leg 200 for connecting to the inner bottom wall of the cabin, and a hinge bracket 300 connecting the seat cushion 100 and the fixed support leg 200.

[0047] The vehicle seat also includes a third limiting member 500 and a fourth limiting member. The third limiting member 500 is connected to the fixed support leg 200, and the fourth limiting member is connected to the hinge bracket. At least a portion of the third limiting member 500 is located within the rotation path of the hinge bracket 300. When the hinge bracket is in a first folded position, the hinge bracket 300 abuts against the third limiting member 500, thus limiting the hinge bracket 300 and preventing it from continuing to flip forward. That is, the third limiting member 500 and the fourth limiting member can cooperate to limit the extreme angle of the hinge bracket 300's flip relative to the fixed support leg 200. The connection method between the third limiting member 500 and the fixed support leg 200 is not limited; for example, they can be fixedly connected or integrally formed. In some embodiments, the fixed support leg 200 is a sheet metal part, and the third limiting member 500 is an extension of the aforementioned sheet metal part.

[0048] In some embodiments, the second flip angle of the seat cushion relative to the hinge bracket, from the second initial posture to the second folded posture, ranges from 84° to 94°. In some specific embodiments, the second flip angle is 89°.

[0049] In some embodiments, the first flip angle of the hinged bracket from the first initial posture to the first folded posture ranges from 63° to 73°. In some specific embodiments, the first flip angle is 68°. It is understood that the sum of the first flip angle and the second flip angle is less than 180°.

[0050] It should be noted that the first and second flip angles mentioned above can be adjusted according to different vehicle models to meet the needs of rear space.

[0051] Please refer to Figure 6 In some embodiments, when the seat cushion 100 is in the second folded position, the center of gravity of the seat cushion 100 is located on the side of the first hinge position 300a away from the second hinge position 300b, that is, on the front side of the first hinge position 300a in the vehicle's longitudinal direction. It should be noted that at this time, the seat cushion 100 abuts against the hinge bracket 300, thus being restricted and unable to flip forward. Since the center of gravity of the seat cushion 100 is on the front side of the first hinge position 300a, the seat cushion 100 has a tendency to continue flipping forward under the action of gravity. This tendency keeps the seat cushion 100 abutting against the hinge bracket 300, thus maintaining the stability of the seat cushion 100's position. It should be noted that when an elastic element for providing resistance is provided at the first hinge position 300a, in order to prevent the seat cushion from flipping backward, the effect of the aforementioned weight is greater than the effect of the elastic element at the first hinge position 300a, thus maintaining the stability of the seat cushion 100's position.

[0052] In some embodiments, when the articulated bracket 300 is in a first folded position and the seat cushion 100 is in a second folded position, the center of gravity of the seat cushion 100 and the articulated bracket 300 as a whole is located on the side of the second hinge position 300b facing the first hinge position 300a, that is, on the front side of the second hinge position 300a in the vehicle's longitudinal direction. It should be noted that at this time, the seat cushion 100 abuts against the articulated bracket 300, and the articulated bracket 300 abuts against the fixed support leg 200, thus being restricted from flipping forward. At this time, the seat cushion 100 and the articulated bracket 300 have a tendency to continue flipping forward under the action of gravity. This tendency keeps the articulated bracket 300 abutting against the fixed support leg 200, thereby maintaining the stability of the articulated bracket 300's position.

[0053] In some embodiments, the inner bottom wall of the cabin has a step, and the fixed support 200 is installed at the step position. Specifically, the fixed support 200 includes a horizontal section 210 and a vertical section 220 connected together, wherein the horizontal section 210 contacts the top surface of the step, the vertical section 220 contacts the side surface of the step, and the second hinge position 300b is located on the horizontal section 210 and away from one end of the vertical section 220.

[0054] Please refer to Figure 4 and Figure 5In some embodiments, at least a portion of the length extension direction of the articulated bracket 300 is deformed to form a clearance groove 300c. When the articulated bracket 300 is in a first initial posture, the clearance groove 300c is located on the front side of the articulated bracket 300 along a first direction. This means that, viewed from the vehicle's own position, it is located on the front side of the articulated bracket 300. The design of the clearance groove 300c allows the articulated bracket 300 to avoid obstacles from steps during tilting, thereby increasing the tilting angle.

[0055] In some specific embodiments, the hinge bracket 300 includes a first bent segment 310, a second bent segment 320 and a third bent segment 330 connected sequentially along the length direction. The first bent segment 310 and the second bent segment 320 intersect at an angle, and the second bent segment 320 and the third bent segment 330 intersect at an angle. The first bent segment 310 and the third bent segment 330 are both inclined towards the front side of the second bent segment 320 in a first direction to jointly define the clearance groove 300c.

[0056] Please refer to Figure 3 In some embodiments, the hinge bracket 300 is a sheet metal part, and the hinge bracket 300 includes a first plate 340 and a first flange 350 connected to both sides of the first plate 340 in the width direction. The first flange 350 is formed by folding along the front side in a first direction, and the first flange 350 is perpendicular to the first plate 340, forming a stable support structure and enhancing the overall strength of the hinge bracket 300.

[0057] It should be noted that the first limiting member and the fourth limiting member can be local areas on the first folded edge 350, that is, the second limiting member 400 can abut against the first folded edge 350 in the first direction, and the third limiting member 500 can abut against the first folded edge 350 in the first direction.

[0058] Furthermore, it also includes a first hinge shaft 600, with a hinge hole opened on the first folded edge 350. The first hinge shaft 600 passes through the hinge hole and the hinge hole on the connector 120 of the cushion 100, thereby realizing the hinge connection between the hinge bracket 300 and the cushion 100.

[0059] In some embodiments, the fixed support 200 includes a second plate and second flanges connected to both sides of the second plate in the length extension direction. The second flanges, located at both ends of the second plate in the Y direction, are formed by folding forward and are perpendicular to the second plate.

[0060] Furthermore, it also includes a second hinge shaft 700, with a hinge hole formed on the second folded edge and a hinge hole also formed on the side of the first folded edge 350 opposite to the connector 120. The second hinge shaft 700 passes through the hinge holes of the first folded edge 350 and the second folded edge, thereby realizing the hinged connection between the hinge bracket 300 and the fixed support leg 200. Both ends of the first hinge shaft 600 and the second hinge shaft 700 are provided with bushings 800, which are used to reduce friction between the hinge shaft and the hinge hole.

[0061] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of protection.
