Description

DETAILED DESCRIPTION OF THE INVENTION (Objects of the Invention) The present invention relates to the structure and function of front-to-back seats.

When seats are lined up one behind the other, such as in a car, the occupants are forced to sit in almost the same posture within a limited space, which causes significant fatigue if they sit for long periods of time. Particularly in the case of regular passenger cars, rear seat occupants are unable to fully stretch their legs, and placing an armrest on the side adjacent to the front seat driver is both structurally and usably undesirable. Both are considered inconvenient and reduce the comfort level of the seats. Furthermore, the structure is suitable for rear seat occupants to effectively protect themselves in case of a collision or sudden stop.

Taking these points into consideration, the present invention not only improves the structure of the rear seat, but also improves the footrests for rear seat occupants and the arm rests for front seat occupants without causing any structural stress. In addition to increasing the comfort of the seat by providing it in a way that does not cause inconvenience or discomfort to the seat occupants,
The purpose is to create a structure that allows those sitting in the back to prop up their legs to ensure their own safety.

(Structure of the Invention) The structure and embodiments of the present invention will be described below using examples of drawings. The subject here is a right-hand drive passenger car that has a structure in which an intermediate platform is provided between the passenger (single person) seat and the driver's seat.

The basic concept of the present invention is as shown in Figure 1 and below.
First, the elbow rest 11 is provided on the right side of the backrest 10 of the passenger seat 1, and the hand rest 21 stored in the intermediate platform box 2 is pulled out, and the two form an armrest. 3 so that the right end of the passenger seat backrest 10 is viewed from the front, and the rear seat is inserted into the cavities 12 and 22 provided below the elbow rest 11 at the right end of the passenger seat backrest and in the intermediate platform box 2, respectively. The structure allows the feet of the sitter to be inserted, and pressure receiving tables 13 and 23 are installed in each cavity.
In addition, by providing reversible auxiliary pressure receiving mechanisms 14 and 24 (including attached blocks 15 and 25) in front of each cavity, the structure is designed to accommodate both front and rear seat occupants. .

Next, add detailed explanations for each part. The shape of the upper surface 110 of the elbow rest 11 is not particularly limited, but as long as it is a rotating surface (for example, a cylindrical surface or a conical surface) centered around the reclining central axis 100, the height of the upper surface 110 will remain constant even if the reclining angle changes. It has the advantage of being kept constant. The cavity 12 is a dead-end hole that opens at the rear, but the wall surface 111 in contact with the waist of the passenger sitting in the passenger seat is made into a curved surface that widens at the rear, as shown in Fig. 1, in order to take the idle space into the cavity, into which the feet are inserted. Provide enough space. Although the mechanism for storing the hand platform 21 in the intermediate platform box is not particularly limited, a case is shown in which a horizontal sliding surface provided at the upper part of the intermediate platform box is used. As shown in FIG. 4, the entrance to the cavity 22 of the intermediate platform box is opened at an angle toward the rear seat occupant. The upper surfaces of the tread pressure receiving tables 13 and 23 are shaped so that the soles of the feet can comfortably touch them. For example, one method is to use green bamboo (cylindrical surface), which is used in health methods. 13 and 23 may be fixed at fixed positions within the cavity, but they may also be moved and fixed at appropriate positions using adhesive cloth or the like. The auxiliary pressure receiving mechanisms 14 and 24 have horizontal shafts 141 and 2, respectively.
41, and can be folded down as shown in the figure and used as a footrest, or the mounting blocks 15 and 25 can be fixed in appropriate positions using adhesive cloth, and the lower limbs can be placed on the lower front surface of the mounting blocks 15 and 25. There are ways to use it, such as by placing the back side (lower calf) or by placing the soles of the feet on the lower back side. Fixed horizontal axis 1
41 is supported by a bracket 142, and the rotation angle position of 14 is regulated by a stopper 143 attached to 141 and a pin 144 attached to 14, and 14 serves as a lid for cavity 12 in the raised position. 24 also has a similar function.

The seat 4 behind the driver's seat is also tilted in the opposite direction to the seat 3 for balance purposes, and the armrest 5 is shaped like a trapezoid as shown in FIG. 1, so that the two people in the rear seat can face each other halfway to facilitate interaction. The center front of the rear seats is wider both front and rear, giving more room to stretch out your legs. In the figure, 6 is a driving handle, 7 is a clutch lever, and 8 and 9 are door-side armrests facing each seater.

If you have a left-hand drive, just change "right" in the explanation to "left." The present invention can also be used in aircraft.

(Effects of the Invention) According to the present invention, a removable armrest is provided on the front seat without causing any unreasonableness in structure or use, and the rear seat occupant can comfortably stretch out their legs, allowing them to easily use the seat during sudden stops. This has the advantage of being able to stand on your feet to ensure your own safety, making it easier to interact with fellow passengers, and having more legroom when sitting in the center of the rear seat, giving you more room to stretch your legs.
