Car seats are an important factor affecting ride comfort, and most cars are designed as five seats, two front seats for drivers and copilot, and three passenger seats for rear row. Because of the limitations of the structure and wheelbase of the automobile, the back row seats are compact, the leg space is small, the angle of the backrest of the back row seats can not be adjusted or can only be finely adjusted, and the sitting for a long time can be uncomfortable. To solve the above problems, some automobile manufacturers lengthen the wheelbase to increase the leg space of the rear seat at the cost of influencing the driving operability, but the improvement of the comfort of the passengers by the above measures is not obvious due to the problem of the angle of the back of the rear seat.
Because the back row seat rarely sits full of three persons at ordinary times, only one to two persons often sit, the back row of certain luxury handlebars is designed to be a two-person seat, and also some automobile manufacturers design the middle seat in the back row to be smaller, and the back is provided with a movable armrest platform.
In view of the foregoing, there is a need for a rear seat for a car that is adapted to a car and that can improve passenger comfort.

As shown in fig. 1,4 and 5, two sides of the backrest of the variable seat 1 are provided with armrest grooves 23 with opening directions facing the front of the vehicle, the armrest grooves 23 are internally provided with armrests 24, the armrests 24 are composed of two hard plates at the bottom and the top and elastic strips (such as rubber strips) connecting the two hard plates, and the hard plates at the bottom are movably connected with the backrest of the variable seat 1 through rotating shafts 27. When the armrest 24 is needed, the armrest 24 can be rotated out of the armrest groove 23, the hard plate at the upper part of the armrest 24 can be folded outwards and downwards into a right angle shape under the pressure of the arm so as to support the arm of a passenger and improve the comfort, and after the passenger removes the arm, the hard plate at the upper part is quickly restored to a state of being clung to the hard plate at the bottom under the elastic action of the elastic strip so as to be convenient to retract into the armrest groove 23. By folding the armrests 24 of the deformable structure, the width of the armrests slot 23 can be reduced, thereby reducing the width of the occupied chair back.
In this embodiment, in order to improve the degree of automation, the first stationary seat 2 and the second stationary seat 3 are each provided with a sensor for detecting whether a person sits above the seat (for example, a pressure sensor provided at the seat cushion, which is connected to a controller 26 provided at the seatback side of the variable seat 1 when the pressure sensor detects that the pressure above the seat cushion exceeds a predetermined range, that is, indicates that a passenger sits on the seat). In the present embodiment, the sensor for detecting whether or not there is a passenger on the first stationary seat 2 is the pressure-controlled switch 25 provided at the side of the seat cushion of the second stationary seat 3, and when the seat cushion of the first stationary seat 2 is folded or taken down, the pressure-controlled switch 25 loses the pressing of the seat cushion of the first stationary seat 2, thereby triggering.
The controller 26 is used for controlling the back angle, the seat cushion angle, the headrest height, the rotation supporting device, the lifting frame 7, the horizontal driving mechanism, the vertical driving mechanism, the box supporting driving mechanism and the like of the variable seat 1 in a remote control or wire control manner, and the controller 26 can detect whether a person is on the first fixed seat 2 and the second fixed seat 3 through the sensor, so as to determine to adopt a proper mode (such as a single person mode, a double person mode and a three person mode) to control the action of the variable seat 1, so as to improve the comfort of passengers, and the specific method is as follows:
the above-mentioned variable seat 1 can follow the first guide rail 6 and remove along the automobile body width direction to make this seat assembly be close to the one side space increase of door, then through rotating strutting arrangement and changing the angle, make variable seat 1 slope to automobile body axis, can be through back of the chair angle adjustment at this moment, become the form of deck chair with variable seat 1 (as shown in fig. 5), the passenger is on the deck chair, leg and foot and shoulder dorsum can extend, thereby with human pressure dispersion at leg and back, improved the travelling comfort.
When there is only one passenger in the rear seat, the seat cushion of the first stationary seat 2 is first removed or folded up (which may also be set to be controlled by the controller 26 to fold electrically) to expose the first rail 6 under the seat cushion of the first stationary seat 2, then the top plate 10 is moved forward to bring the top plate 10 into substantial alignment with the bottom plate 8, at which time the position of the variable seat 1 has avoided the seat back position of the first stationary seat 2 and thus can be moved laterally along the first rail 6, after the variable seat 1 has been moved to the middle or other suitable position, the variable seat 1 is rotated and its seat back angle is adjusted backwards to deform the variable seat 1 into a recliner chair, while the leg rest 4 and the foot rest 5 are extended to support the legs and feet of the passenger. Of course, instead of the leg rest 4 and the foot rest 5, the feet may be placed directly on the seat cushion of the second stationary seat 3, or the feet may be inserted into the leg rest box 21 at the back of the third stationary seat 19. In order to reduce the space occupied by the variable seat 1 and thereby increase the angle of rearward adjustment of the seat back thereof, it is preferable to lower the headrest thereof to the lowest position, and in order to improve stability, the seat cushion of the variable seat 1 may be adjusted to a front-high rear-low mode by the lifter 7.
Unlike the single person mode described above, in which the seat cushion of the first stationary seat 2 is first removed or folded up (which may also be controlled by the controller 26) to expose the first rail 6 below the seat cushion of the first stationary seat 2, and then the top plate 10 is moved forward to bring the top plate 10 into substantial alignment with the floor 8, where the position of the variable seat 1 has avoided the seat back position of the first stationary seat 2 and is thus movable laterally along the first rail 6, the seat cushion of the first stationary seat 2 is first removed or folded up (which may also be controlled by the controller 26) to expose the first rail 6 below the seat cushion of the first stationary seat 2, and in which the position of the variable seat 1 has been moved away from the seat back position of the first stationary seat 2 and is thus laterally movable along the first rail 6, it is noted that the second stationary seat 3 is not touched by the user when the variable seat 1 is to be changed to a recliner, and the lifting frame 7 must be raised to space the legs of the passenger on the second stationary seat 3, while the lifting and lowering the leg boxes 21 must also be raised and limited by the space of the legs of the passenger on the second stationary seat 3.
When the rear row is full of three passengers, the seat cushion of the first stationary seat 2 is not movable at this time, the variable seat 1 can be moved only a small amount simply forward and backward, and the posture of the variable seat 1 is adjusted by the up-down lifting function of the lifter 7 and the seat posture adjusting function of itself to improve comfort.
In order to ensure safety, the belt of the variable seat 1 must be of a properly increased length so that the belt will still function properly when the variable seat 1 is deformed into a recliner. When the supporting component and the lifting plate of the trapezoid cabinet are not used, the safety belt on the first fixed seat 2 can be inserted under the seat cushion of the variable seat 1 or under the front part of the first guide rail 6 (as shown in fig. 4), and passengers on the variable seat 1 can be prevented from rolling off the seat when braking, so that safety is improved.
As can be seen from the above description, the variable seat 1 may be disposed not only on the rear row side but also in the middle position of the rear row, as long as the position of the variable seat 1 is moved, so that the variable seat 1 obtains enough space to be unfolded into the reclining chair state, and the description thereof is omitted.
While the invention has been described above with reference to the accompanying drawings, it will be apparent that the specific design of the invention is not limited by the foregoing, but it is within the scope of the invention to apply the inventive concept and technical scheme directly to other occasions without any substantial improvement or improvement.
