Abstract

A car seat with a moving backrest is a transformer seat that allows a person to comfortably sit in it, facing the windshield and the rear seats of the passenger compartment.

This chair will be widely used as the front seats of the car, as it allows you to create more comfortable conditions when communicating between all passengers of the car during parking.

The movement of the back of the chair is possible due to the presence of a throwing mechanism in the chair, which moves the back of the chair from one edge of the seat to the other with a flip of the back surface by 180 degrees, which leads to a turn of the working surface of the chair in the opposite direction. Depending on the method of execution of the throwing mechanism, there are several options for moving the chair back and turning it 180 degrees. The presence of a mechanism for adjusting the angle of inclination of the chair, the seat and back of the chair allows you to choose the most comfortable position for the chair for each user.

In the manufacture of a chair with a moving backrest, materials and technologies are widely used in industry in the manufacture of car seats.

Description

The angle adjustment of the seat and backrest is carried out by the mechanism described in Figure No. 1 and is widely used in the automotive industry. The matching item numbers of Figure 2 and Figure 1 correspond to the same elements of the model in question. Implementation of a utility model. All elements of the chair are made of materials widely used in the automotive industry, the technical solution of many mechanisms of the chair is also widely distributed and used in industrial car seats. So, for example, mechanisms for adjusting the movements of the chair back and forth, up and down, as well as changing the angle of the seat and backrest, are available for many car seats installed in cars. The movement of the seatback from one edge of the seat to the other, as shown in Figure 1, is as follows. First, [you need to unlock the back of the chair (key 2). To do this, pull the handle] of the latch (key 16) up, as a result of which the lock will exit (key 17)

from the blocking hole in the pipe (pos. 18) and the back of the chair will be able to rotate freely on the pin (pos. 7) around the C axis. We will expand the chair back 180 degrees and insert the lock into the pipe hole by pressing the lock knob (pos. 16) down . The back will be fixed in the pipe (pos. 18) and will not be able to rotate around; Axis C. Then, after unlocking the knee of the seat (pos. 3), by pulling the blocker (pos. 15) to the side of the seat (in figure No. 1 on us), the knee of the seat (pos. 3) will be disconnected with the seat body, in which there is a hole for installing the lock (key 15). Now, move the jumper of the seat knee (key 19) relative to Axis A, from this edge of the seat to the opposite with the simultaneous rotation of the angle adjustment knob (key 12) between the seat and the back of the chair. The angle between the seat and the back of the chair is set so that it would be convenient for a person to sit in the chair after transforming the back into a new position. For faster movement of the seatback from one edge of the seat to the other, it is advisable to use a mechanism for adjusting the angle between the seat and backrest such that it would temporarily disconnect the large gear (pos. 14) of the mechanism from the small (pos. 13). This would allow the backrest to rotate freely on the jumper (key 19) around Axis B and therefore would accelerate the change in angle between the seat and the back of the chair, which is necessary when moving the backrest from one edge to the other.

Name of utility model: Car seat with a moving back, from one edge of the seat to the other.

The model proposed for consideration is a transformer car seat, capable of changing the direction of the surface of the working position in the opposite direction.

The technical field of the presented model is the automotive industry. Widespread use, this chair will find as the front seats of cars. The presence of the proposed seats in the car will allow more efficient use of the car during parking. So, the seat in question allows the driver and front passenger to sit in their seats facing the rear seat passengers, which will create more comfortable conditions for communication.

The level of technology of the presented model. Analogs of the presented model include car seats, widely used in the automotive industry and installed in cars. Car seats are made using different technologies and using different materials. Automotive seats manufactured by the industry have several types of internal frames made either from tubular materials or from a solid cast construction. Some manufacturers fill the chair frame with polyurethane foam, others attach to the frame pillows containing: horsehair, orthopedic springs, foam rubber, other elastic materials. The outer surface of the chair is covered with upholstery material, such as: velor, genuine leather, leatherette. The shape and material of car seats is chosen in such a way that would most fully satisfy all the needs of a person in the process of operating a car. (Source of information: www.recato.rn, www.d-mir.ru / Cars and prices, articles, auto-tuning /, www.unp.ru).

A common feature of the produced car seats and the presented model is the use of traditional materials used in the manufacture of car seats, as well as the presence of seat and backrest adjustments. A distinctive feature of manufactured car seats and the model presented is that industrial car seats do not have a seat back that can move to the opposite side of the seat, and therefore are not able to transform (change the position of their parts) in such a way as to ensure that the working surface of the chair turns into in the opposite direction, while the model of chair presented for consideration contains a backrest due to the movement of which the person is comfortably located in two mutual but in opposite directions.

The disadvantage of the manufactured car seats is the inability to ensure a comfortable position of a person in it facing the rear seats, when communicating with the rear passengers, you must always turn your head back or sit sideways on the seat of your chair. The model of a car seat proposed for consideration is devoid of these drawbacks and allows a person to conveniently sit on the front seats both facing the windshield and the rear seat. This advantage provides ease of communication between passengers during parking.

At present (in the absence of industrial designs and information in the media), no one is releasing car seats with a backrest to the opposite edge of the seat, which allows us to consider this device as [a new technology product that extends the variety of car seats and solves the problem of comfortable people in car interior while parking.

The main essential feature of the claimed model, which influences the achievement of the technical result, is the presence of a folding mechanism for the car seat, which can move the seat back from one edge of the seat to the other with a 180 degree flip, so that the working surface of the seat (the surface of the person’s location) turns out to be deployed in the opposite direction from the original position. The objective of the claimed model is the ability of the seat to be transformed in such a way that would allow the user to sit in the chair equally comfortably, both facing the windshield and the rear seats of the car. A brief description of the drawings. You can move the back of the chair from one edge of the seat to the other in different ways, some of which are shown in Figure No. 1 and Figure No. 2. Consider the method of moving the back of the chair shown in Figure No. 1. With this method, the backrest is moved due to the knee of the seat (pos. 3) being thrown from one extreme, fixed position to another, and the backrest is rotated 180 degrees due to the possibility of the backrest rotating on the pin (pos. 7) relative to the C axis Figure 1 shows the position of the chair in which the working surface of the chair is directed toward the windshield. Figure No. 2 depicts the moment of transformation of the chair at which the seat knee (pos. 3) moves from one extreme position to another, as well as a 180-degree turn of the back of the chair relative to Axis C. Figure No. 3 depicts the position of the chair at which the working surface the seat is directed towards the rear seat of the car. The Figure No. 4 shows the details of the throwing mechanism and the node for changing the angle of inclination of the seat and back of the chair. The chair is able to move back and forth relative to the windshield, due to the runners located in the guide mounts (pos. 5), which are fixed in the floor of the car. The chair is moved up and down relative to the floor of the car, due to the micro-lift (pos. 6), by adjusting the body pressure acting on the seat of the chair, the required seat height level is set, with its subsequent fixation. All of the above adjustment mechanisms are widely used in automobile and office seats manufactured by the industry. The angle of inclination of the seat of the chair relative to the floor of the car is carried out by rotating the small gear (pos. 10) whose axis is mounted on the housing of the lifting mechanism (pos. 8) for its handle (pos. 9). In this case, the rotation of the large gear (pos. 11) takes place, which is fixed to the seat casing, and its center of rotation coincides with Axis A. Thus, as a result of the rotation of the handle (pos. 9), the seat angle of the chair changes along axis A, relative to car floor. A change in the angle of inclination of the back of the chair relative to the seat occurs as a result of rotation of the small gear (pos. 13) for the handle (pos. 12), the axis of rotation of which is fixed on the knee of the seat (pos. 3). The small gear (pos. 13) rotates the large gear (pos. 14), mounted on the pipe (pos. 18), which, in turn, is mounted on the jumper of the seat knee (pos. 19), and rotates freely on it, and the axis of rotation of the pipe (pos. 18) coincides with Axis B.

To the central part of the pipe (pos. 18), perpendicular to the Axis B, a pin (pos. 7) is mounted on which the back of the chair is mounted (pos. 2). Thus, turning the handle (pos. 12), the pipe (pos. 18) rotates relative to the B axis, and therefore there is a change in the angle of the chair backrest (pos. 2) relative to the seat (pos. 1). Due to the fact that the radii of the gears (pos. 10), (pos. 13) and gears (pos. 11), (pos. 14) are different, they work in the gearbox mode. Rotating: the handles (pos. 9) and (pos. 12), torque is transmitted from the small axis; gears on the axis of the large gears, while there is an increase in power and a decrease in the number of revolutions on the shaft of large gears. The described mechanism for adjusting the angle of the seat and backrest is also widely used in the automotive industry.

The throwing mechanism of the back of the chair is a U-shaped structure fixed by two ends to the body of the lifting mechanism (pos. 8) in the middle of the side of the seat of the chair (pos. 1), along Axis A. Throwing: the mechanism is capable of rotating around Axis A, move your jumper (key 19) from one edge of the seat to the other. The U-shaped design of the throwing mechanism has two fixed positions. Due to the latch (key 15), located on the knee of the seat (key 3) of the throwing mechanism, it is fixed to the seat body (key 1), while the jumper (key 19) of the mechanism is either at the front or rear the edges of the seat. The elements of the throwing mechanism located on both sides of the seat are metal plates and are called the seat knee (key 3). The element of the throwing mechanism, located along the B axis, is a round jumper (key 19) rigidly connecting the two longitudinal knees of the seat (key 3), which gives the entire mechanism a U-shaped shape. A pipe (pos. 18) is put on the round jumper of the mechanism (key 19), which is able to rotate on the jumper around Axis B. To the central part of the pipe (key 18), perpendicular to Axis B, a round cross-section pin is attached (pos. 7). The back of the chair (pos. 2) is strung onto the pin (pos. 7), on which it is able to rotate around the C axis. The back of the chair has two fixed positions. Due to the latch (key 17), the backrest frame is rigidly fixed to the pipe (key 18), while the working surface of the backrest is directed either forward or backward of the passenger compartment. When lowering and raising the lock knob (pos. 16), the backrest is locked and unlocked.

Figure 2 shows another way to move the back of a chair from one: the edges of the seat to the other. With this method, the throwing mechanism has the shape of two articular knee, and the back of the chair is able to turn 180 degrees around the D axis, passing through the end of the knee of the back (pos. 4) of the throwing mechanism. Figure number 5 depicts the working position of the seat directed towards the windshield of the car. Figure 6 depicts the moment of transformation of the chair, in which the swinging mechanism, fixed to 1 seat of the chair along Axis A, moves relative to this Axis, from one edge of the seat to the other, and the back of the chair turns 180 degrees. Figure 7 shows the location of the chair, the working surface of which is directed to the rear seats; car interior. The elbow of the seat (pos. 3), the swinging mechanism, has two fixed positions, in which the elbow is rigidly fixed to the seat using a lock. The back of the chair is also fixed to the knee of the back (pos. 4) after a 180-degree turn.
