Description

Rear seat assembly with variable seat structure

The present invention relates to a rear seat assembly having a seat variable structure, and in particular, the seat variable device having a simple structure on the lower surface of the seat cushion of the rear seat allows the user to easily and conveniently select the front and rear seats at a selective position and angle. The rear seat assembly is provided with a variable seat structure that can improve the productability and customer satisfaction of the product because the sliding seat adjustment allows passengers in the rear seat of the vehicle to take a comfortable position.

Seats generally used in automobiles are ergonomically shaped to support passengers safely and comfortably within a limited space and weight range, and the driver's seat and the passenger seat (front) according to the arrangement in the passenger compartment of the vehicle. Seat) and rear magnet (rear seat). According to the shape, it is classified into a bench seat in the form of a chaise longue and a separate seat in which a seat can be seated separately.

The front seat is provided with a pair of seat adjusters which slide forward and backward provided under the seat cushion so that the driver can take an optimal driving posture, and the seat back is freely adjusted to rest or lay down the seat. Reclining lever devices are formed, each of which is adapted to take a grip.

The rear seat is largely divided into two parts, a seat cushion for supporting the passenger's hips and thighs, and a seat back for supporting the waist and the back. A head rest is provided that protrudes to support the driver's head.

There is also a rear seat in the middle of the seat back is provided with an arm rest that the lower end is hinged and rotated according to the user's selection.

The seat cushion and seat back of the rear seat include a seat frame constituting a skeleton, a seat pad filled in the seat with a foamed rubber material, and a seat fabric made of fabric paper to cover the surface of the seat frame and the seat pad. )

A conventional vehicle rear seat consisting of a seat cushion as described above, and a seat back having an arm rest and a head rest is briefly described with reference to FIGS. 1 and 2.

As a seat cushion 10 for supporting the thigh of the rear passengers (from the hip to the thigh), and the lower end is connected to the upper portion of the rear end of the seat cushion 10 to support the back and back of the passenger Consists of.

Here, the seat back 20 is formed of a seat frame made of a skeleton, a seat pad filled with a foamed rubber material in the seat back, and a sheet fabric which is a woven paper covering the entire outer surface of the seat frame and the seat pad. Arms that are formed at the upper both sides of the upper part of the headrest for supporting the head of the passenger on board and integrally formed and the lower end is hinged to the center portion of the seat back 20 is rotated according to the user's selection A rest is provided.

On the other hand, the driving motor is operated by a button operation so that the rear seat occupant can take the optimal position, and the seat cushion 10 slides before and after, so that the position of the seat cushion 10 and the angle of the seat back 20 can be freely There is also a rear seat with an adjustable power seat.

However, such a conventional rear seat has a lower side of the cushion and an upper end of both the seat back and the rear end fastened to the floor panel upper side and the package tray front end, respectively, so that the passenger in the rear seat cannot take an optimal position, so it is very difficult to move long distances. Since it is inconvenient, it does not satisfy various needs of customers, and thus, there is a disadvantage that the merchandise for the product is lowered.

In addition, the rear seat, which is formed by sliding the front and rear seat cushions by operating the motor by the button operation, can seat the passenger in a comfortable position in the rear seat, but it is complicated in structure so that many parts are used. There was a problem of increased airlift, increased production cost of the product, and lowered productivity.

Accordingly, the present invention has been made to solve the fundamental problems of the prior art, the object of which is a simple structure on the lower surface of the seat cushion of the rear seat is provided with a seat variable device that is easy and convenient to operate the user's selective position and By adjusting the rear seats at an angle, passengers in the rear seats of the vehicle can take a comfortable position when traveling long distances, which improves the assembly of the product, reduces labor and productivity, and satisfies the product's various needs and customers' practical needs. It is to provide a rear seat assembly having a seat variable structure that can be made.
