[0028] The present invention will be further described below with reference to specific embodiments:

[0029] A reversible seat is provided in a vehicle. The vehicle includes a frame 1, a fixed seat 2, a table 3, and the reversible seat 4. The frame 1 has a chassis 11. The fixed seat 2 is mounted on the chassis 11 for a user to sit on. The table 3 is mounted on the chassis 11 and located on one side of the fixed seat 2. The reversible seat 4 is located on one side of the table 3. The reversible seat 4 has a reversing component for adjusting the orientation of the reversible seat 4 so that the reversible seat 4 faces the table 3.

[0030] like Figure 1As shown, the vehicle in this patent is a sightseeing vehicle. The frame 1 is equipped with a front suspension assembly 13, with an instrument panel and steering wheel mounted above the front suspension assembly 13, and a front wheel 131 mounted below the front suspension assembly 13. A rear suspension assembly 14 is located at the rear of the frame 1, with a rear wheel 141 mounted below the rear suspension assembly 14. The chassis 11 is located between the front suspension assembly 13 and the rear suspension assembly 14, and the fixed seat 2, table 3, and reversible seat 4 are mounted on the chassis 11.

[0031] Normally, a vehicle has front seats and rear seats. The front seats are located near the dashboard and are used for the driver and front passenger; the rear seats are for passengers to sit comfortably and enjoy the view. Figure 1 As shown, the vehicle in this patent has two rows of seats, namely front seats and rear seats. The rear seats are fixed seats 2, which are fixed to the chassis 11. They include a first fixed seat 2a facing the direction of vehicle travel and a second fixed seat 2b facing one side of the vehicle. The second fixed seat 2b is located behind and close to the driver's seat, creating a seating space between the second fixed seat 2b and the first fixed seat 2a. A table 3 is provided on the chassis 11 facing between the first fixed seat 2a and the second fixed seat 2b. Users can sit on the first fixed seat 2a and the second fixed seat 2b to use the table 3 for simple gatherings or work conversations. The reversible seat 4 can be either the front passenger seat or the driver's seat, such as... Figure 1 , 2 As shown in this patent, the table 3 is located behind the passenger seat, and correspondingly, the passenger seat is configured as a reversible seat 4.

[0032] In this patent, the reversible seat 4 includes a seat cushion assembly 41, and the reversing assembly includes a sliding unit 42, through which a backrest assembly 43 is connected. The sliding unit 42 is used to slide the backrest assembly 43 to the front and rear ends of the seat cushion assembly 41 to adjust the orientation of the reversible seat 4. The reversing assembly also includes positioning units 44 for positioning the backrest assembly 43 at both ends of the seat cushion assembly 41. Figure 2 As shown, the chassis 11 is provided with a support 45, which is specifically a square box. The top of the box is formed with a mounting surface 451, on which the seat cushion assembly 41 and the sliding unit 42 are fixed.

[0033] In this patent, the mounting plane 451 is provided with a plurality of support feet 453, and the seat cushion assembly 41 in this patent is fixed to the support feet 453 by a screw structure. The sliding unit 42 includes slide rails 421 disposed on both sides of the seat cushion assembly 41, and sliders 422 are slidably disposed on the slide rails 421, and the backrest assembly 43 is connected through the sliders 422. The backrest assembly 43 is vertically positioned above the seat cushion assembly 41. Since the seat cushion assembly 41 in this patent has slide rails 421 on both sides, sliders 422 on the slide rails 421 are respectively connected to the left and right sides of the backrest assembly 43. The sliders 422 support the backrest assembly 43, allowing it to suspend above the seat cushion assembly 41. The user can adjust the position of the backrest assembly 43 by sliding it. When the backrest assembly 43 is at the front end of the seat cushion assembly 41, the entire reversible seat 4 faces the table 3. When the backrest assembly 43 is at the rear end of the seat cushion assembly 41, the entire reversible seat 4 faces the front of the vehicle for the front passenger seat. After the backrest assembly 43 has slid, its position is fixed by the positioning unit 44, thus allowing the reversible seat 4 to be in different orientations to meet different user needs and increase the flexibility of vehicle use.

[0034] like Figure 3As shown, the positioning unit 44 includes a support rod 441 welded to the slider 422. The support rod 441 is horizontally positioned in the sliding space below the seat cushion assembly 41 and above the support 45. The support rod 441 has an extension 444 on its front and rear sides. The extension 444 is a square plate with a locking hole 442. It also includes two locking pins 443, which are installed on the front and rear ends of the support 45. The support 45 has an operating groove on its front and rear sides. The locking pins 443 are inserted into the top of the operating groove and extend upward through the support 45. The operating groove has a reset member for driving the locking pins 443 to move up and down. When the backrest assembly 43 slides onto one end of the support 45, the user can use the operating groove to allow the reset member to drive the locking pin 443 downwards. When the locking pin 443 is aligned with the locking hole 442 on the extension 444, the user can release the locking pin 443 so that it is inserted into the locking hole 442 under the action of the reset member to lock it. When the backrest assembly 43 needs to be adjusted, the user can manually operate the locking pin 443 to disengage it from the locking hole 442. The support rod 411 connects two sliders 422 on the left and right sides, increasing the stability of the sliders 422 during sliding. Furthermore, the sequential connection of the support rod 411, sliders 422, and backrest assembly 43 forms a complete frame, further increasing the stability of the entire backrest assembly 43 during sliding. Furthermore, by placing the support link 411 below the seat cushion assembly 41 to conceal the positioning unit 44, the positioning unit 44 is prevented from contacting the outside world, thus affecting its normal use, and the overall aesthetics are enhanced.

[0035] Furthermore, the slider 422 has a protrusion 4221 on the side away from the seat cushion assembly 41, and a connecting plate 423 is connected to the protrusion 4221. The outer end of the connecting plate 423 is offset towards one side of the backrest assembly 43 and connected to the backrest assembly 43. The backrest assembly 43 includes a backrest frame 431 and a backrest cushion 433 disposed outside the backrest frame 431. The backrest frame 431 includes a backrest connecting seat 432. One end of the connecting plate 423 is attached to the outside of the backrest cushion 433 and connected to the backrest connecting seat 432 located inside the backrest cushion 433 by fasteners. Figure 3As shown, the protrusion 4221 is formed on the outer side of the slider 422, and the connecting plate 423 is also fixed on the outer side of the slider 422. It forms a space for the seat cushion assembly 41 within the slider 4221, preventing the seat cushion assembly 41 from deforming and contacting the slider 422, thus preventing wear. The connecting plate 423 is connected to the slider 422 by screws. The connecting plate 423 has an adapter hole 4232 and a strip hole 4231 on one side of the adapter hole 4232. Fasteners are installed in the adapter hole 4232 to connect the backrest assembly 43 and the slider 422, or to adjust the offset angle of the backrest assembly 43 when the fasteners in the adapter hole 4232 become loose. Fasteners are installed in the strip hole 4231 to position the offset backrest assembly 43. The fasteners are generally screws. During installation, the tilt angle of the backrest assembly 43 can be adjusted by loosening the screws in the adapter hole 4232 and then tightening the screws in the adapter hole 4232 and the screws in the strip hole 4231 to position the current tilt angle of the backrest assembly 43, thereby realizing the angle adjustment of the backrest assembly 43.

[0036] In other embodiments, a slide rail 421 and a slider 422 may be provided only on one side of the seat cushion assembly 41. Providing slide rails 421 and sliders 422 on both sides of the seat cushion assembly 41 helps increase the stability of the backrest assembly 43 after installation. In other embodiments, the driver's seat may also be configured as a reversible seat 4, depending on the user's specific needs. In summary, this patent, through the use of a reversible seat 4 in conjunction with a table 3, allows for adjustments to the interior layout of the vehicle, thereby meeting the user's diverse entertainment needs. Furthermore, the reversing component in this patent is convenient and quick to adjust, facilitating rapid user adjustments.

[0037] In other embodiments, the sliding unit 42 may also be a drive motor installed in the support, which drives a slider 422. The slider 422 is then connected to the backrest assembly 43 through a connecting plate 423. The automatic sliding of the backrest assembly 43 is achieved by driving the slider 422 through the drive motor.
