Abstract
Description
Technical Field
[0001] The utility model relates to the field of vehicles, in particular to a multifunctional vehicle seat and a seat assembly having the multifunctional vehicle seat. Background Art
[0002] The rear row (second row or third row) electric seats of existing passenger cars usually adopt a split bench form (the ratio is generally 60-40 or 50-50), or a 100% bench form. Such seats can seat 2 to 3 people. However, due to the absence of an armrest in the middle, the comfort of such seats is not high, especially when there are 2 people or even only 1 person sitting.
[0003] Currently, such split electric seats are generally used as rear seats in the market. They adopt a 40-20-40 ratio bench form, with the middle part accounting for 20% of the seat, and the left and right sides each accounting for 40%. The backrest of the middle part can be folded down 90 degrees to serve as the armrests of the left and right seats, thus converting to a two-person seat structure. When 3 people need to be seated, the backrest of the middle part can be retracted to its original position. However, currently, the left and right sides of such electric seats cannot be adjusted left and right to avoid the front and rear wheels, so the left and right seats cannot be adjusted to all angles to achieve the leisure function (especially the zero-gravity seat).
[0004] In addition, there is no such electric seat assembly that can automatically switch between a three-person seat structure and a two-person seat structure. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the above-mentioned drawbacks. Therefore, it is desirable that the left and right sides of the rear seat can be adjusted left and right to avoid the front and rear wheels, so as to allow the left and right seats to be adjusted to all angles to achieve the leisure function. It is also desirable. It is also desirable that the middle part can not only be used as the armrests of the left and right sides of the rear seat, but also be used as a small table, for example, located between the second row seats. Moreover, the middle part can be flipped up and moved backward to create more space, and the middle part can be telescoped in the left-right direction to leave more adjustment space for the left and right sides. In addition, it is desirable that the middle part can be adjusted into a rear-facing seat for use during the activities of the occupants, such as fishing during vacations.
[0006] To this end, the utility model provides a multifunctional electric seat, which can be used in a seat assembly, such as the second and / or third row seats in the rear row, especially the second row seat, to automatically switch between a three-person seat structure and a two-person seat structure.
[0007] Specifically, the present utility model provides a multi-functional seat, which includes a seat cushion and a backrest. According to an embodiment, the multi-functional seat can be converted into at least a first position and a second position. In the first position, the multi-functional seat is used as a normal seat, wherein the seat cushion is in a nearly flat posture and the backrest is nearly upright. In the second position, relative to the first position, the seat cushion is flipped upward to a nearly upright posture and the backrest is rotated backward to a nearly flat posture.
[0008] According to an embodiment, each of the seat cushion and the backrest includes a main body and sliding plates located on the left and right sides of the main body and capable of protruding and retracting relative to the main body in the left and right directions, so that the seat cushion and the backrest can be converted between a protruding position and a retracting position. For this purpose, the multi-functional seat further includes a first drive motor for driving the sliding plates to protrude and retract relative to the main body.
[0009] With this arrangement, the width of the multi-functional seat in the left and right directions can be adjusted. When converted to the protruding position and used as the middle seat of the rear row seats, the multi-functional seat can provide sufficient seating space for the occupants and sufficient armrest space for the left and right seats of the rear row seats when the backrest is folded forward. On the other hand, when converted to the retracting position, the multi-functional seat leaves adjustment space for the left and right seats to allow the left and right seats to be adjusted inward to avoid the front and rear wheels.
[0010] According to an embodiment, the seat cushion is movably mounted on the vehicle floor, and the multi-functional seat further includes a height adjustment mechanism for adjusting the height of the multi-functional seat, a length adjustment mechanism for adjusting the forward and backward movement of the multi-functional seat, and a recliner for adjusting the angle of the backrest relative to the seat cushion. According to an embodiment, the length adjustment mechanism includes a guide rail for guiding the movement of the multi-functional seat. With this arrangement, when used as the middle seat of the rear row seats, the height of the multi-functional seat can be matched with the height of the left and right seats, and when converted to the retracting position, the height of the multi-functional seat can be reduced and moved backward to facilitate leaving more adjustment space for the left and right seats.
[0011] According to an embodiment, a fixing hook can be arranged at the front end of the guide rail for releasably fixing the multi-functional seat, specifically the seat cushion. In the first position, the seat cushion is fixed to the fixing hook, and in the second position, the seat cushion is detached from the fixing hook. When moving from the first position to the second position, the multi-functional seat first moves backward a certain distance, then detaches from the fixing hook, and then the seat cushion is flipped upward.
[0012] According to another embodiment, the seat cushion is fixed to the vehicle floor, and the multi-functional seat further includes a recliner for adjusting the angle of the backrest relative to the seat cushion. In this case, the multi-functional seat does not include a height adjustment mechanism and a length adjustment mechanism, thereby reducing costs.
[0013] According to an embodiment, in the first position, the skateboards on both sides of the backrest and the seat cushion body are in the extended positions.
[0014] According to an embodiment, in the second position, the skateboards on both sides of the backrest and the seat cushion body are in the extended positions. In this case, the multi-functional seat further includes a support leg provided on the back surface of the backrest, which is received in the backrest in the first position and pops out from the backrest in the second position to support on the vehicle floor. With this arrangement, the multi-functional seat can act as a rear-facing seat, where the seat cushion is converted into the backrest of the seat and the backrest is converted into the seat cushion of the seat.
[0015] According to an embodiment, the multi-functional seat can also be converted into a third position. In the third position, relative to the first position, the seat cushion flips upward to a nearly upright posture, the backrest remains in a nearly upright posture, and the multi-functional seat moves backward. For this purpose, the multi-functional seat further includes a second drive motor for driving the seat cushion to flip upward. With this arrangement, the multi-functional seat can create more space.
[0016] According to an embodiment, the multi-functional seat can also be converted into a fourth position and a fifth position. In the fourth position, the multi-functional seat moves to the foremost position, in the fifth position, the multi-functional seat moves to the middle position, and in the fourth and fifth positions, the backrests are both folded forward. With this arrangement, the multi-functional seat can act as an armrest and a small table. In addition, in the second position, the multi-functional seat moves to the rearmost position.
[0017] In addition, the present utility model provides a seat assembly, which includes the above multi-functional seat, and this multi-functional seat is used as the middle seat of the seat assembly. For example, the seat assembly can be split type, with a ratio of 40-20-40, that is, the middle seat occupies 20% and the seats on the left and right sides each occupy 40%.
[0018] According to an embodiment, the seats on the left and right sides can move toward and away from each other left and right and / or can move forward and backward.
[0019] According to an embodiment, the seats on the left and right sides can rotate 180 degrees so that they face backward. In this case, when the multi-functional seat is in the fifth position, it can act as a small table between the second row seat and the third seat.
[0020] According to the multi-functional seat of the present utility model, when three people need to sit on the rear seats, the multi-functional vehicle seat can be converted into the middle part of the seat assembly to be used as a normal seat. In this case, the multi-functional seat is in the first position, and both the backrest and the seat cushion are in the extended position to provide a larger seating area for the occupants. When two or one person needs to sit on the rear seats, the multi-functional seat can be converted into an armrest to improve the comfort of the occupants on the left and right sides. In this case, the multi-functional seat is in the fourth position. Moreover, both the backrest and the seat cushion can be in the retracted position, enabling the multi-functional seat to be telescopic in the left-right direction, thereby leaving an adjustment space for the left and right sides of the rear seats, facilitating the adjustment of the left and right sides to avoid the front and rear wheels. Thus, the seats on the left and right sides can be adjusted to all angles to achieve the leisure function without interference with the front and rear wheels. The multi-functional seat can also be converted into an upward-flipping mode to create more space, where the multi-functional seat is in the third position. The multi-functional seat can also be converted into a rear-facing seat for the occupants to sit during activities, such as when fishing, where the multi-functional seat is in the second position. In addition, the multi-functional vehicle seat can be converted into a small table between the second-row seat and the third-row seat, where the second-row seat can rotate 180 degrees, and the multi-functional seat is in the fifth position.

As Figures 4A - 5B shown, the multifunctional seat 100 further includes drive motors 170 (one on each of the left and right sides) for driving the slides to extend and retract relative to the bodies. In addition, the multifunctional seat 100 includes a height adjustment mechanism (not shown) for adjusting the height of the multifunctional seat, a recliner 130 for adjusting the angle of the backrest 110 relative to the seat cushion 120, and a guide rail 150 for guiding the multifunctional seat 100 to move forward and backward, and a fixing hook 180 is arranged at the front end of the guide rail 150 for releasably fixing the multifunctional seat 100, specifically the seat cushion 120.
[0033] Figure 1 Show the multifunctional seat 100 converted to the first position, in which the multifunctional seat 100 is used as a normal seat, where the seat cushion 120 is in a nearly flat position, the backrest 110 is nearly upright, and both the backrest 110 and the seat cushion 120 are in the extended position.
[0034] Figure 2A And Figure 2B Show the multifunctional seat 100 converted to the second position, in which, relative toFigure 1 In the first position shown, the seat cushion 120 is turned upward to a nearly upright position to serve as a backrest, and the backrest 110 is rotated backward by a certain angle to a nearly flat position to serve as a seat cushion. Both the backrest 110 and the seat cushion 120 remain in the extended position. For this purpose, the multifunctional seat 100 further includes a drive motor 150 for driving the seat cushion 120 to turn upward. In addition, a guide rail 150 is fixed to the vehicle floor 10 such that the seat cushion 120 is movably mounted on the vehicle floor. The multifunctional seat 100 further includes a support leg 160 provided on the back surface of the backrest 110. In the first position, it is retracted into the backrest 110, and in the second position, it pops out from the backrest 110 to support on the vehicle floor 10. When moving from the first position to the second position, the multifunctional seat 100 first moves backward a certain distance, then disengages from the fixed hook 180, and then the seat cushion 120 turns upward.
