Description

DESCRIPTION ADJUSTMENT MECHANISM FOR BACK SUPPORT FOR VEHICLE SEATS Technical Area The invention relates to a back support mechanism for vehicle seats.

The invention especially focuses on the waist of the users in the car seats used in the automotive sector. Developed to provide support to the user's seat lumbar support, with an adjustment mechanism for back support for vehicle seats State of the Art A comfortable ride and journey of the users in the car seats in the automotive various supports that provide support to the lumbar regions to enable them to perform mechanisms and apparatus have been developed.

The lumbar support mechanisms used in current applications are the result of a large number of parts. It has a complex structure formed by the combination of In some mechanisms There are gear wheel systems and all gear wheels are available to repair when gears fail. system needs to be changed. The springs used in the inner part of the mechanism After a certain period of time, its effect may decrease. In some mechanisms, electric motors are used, but since an additional power line is required for the control of these motors. the structure becomes complex and additional elements are needed. Apart from that, electric in motorized mechanisms, on the edge of the seat in a space equal to the volume of the electric motor must exist. found. In the application in question, the adjusting device for the Bowden cable arrangement is explained. Adjustment for the Bowden cable arrangement, which is the subject of the application device. Includes manual lock or tension lock. The adjusting device is also a housing, it includes a helical shaft and two half-shell sections. pelvis, especially in a vehicle seat and/or it is used to support the lumbar region. However, described here The adjusting device has a very complex structure and consists of a large number of elements. is formed. It contains an actuator to provide the rotational movement. Here a device that does not take up space in the seat, which will prevent the mechanism from running idle. mechanism is not mentioned.

As a result, due to the above-mentioned disadvantages and current solutions It is necessary to make an improvement in the relevant technical field due to the inadequacy of the is locked.

Purpose of the Invention The invention was created by being inspired by the current situations, and the above-mentioned negativities aims to solve.

The main purpose of the invention is to increase the waist of the users in the car seats used in the automotive sector. Developed to provide support to the user's seat lumbar support, adjustment mechanism for back support for vehicle seats is to reveal.

Another object of the invention is that it occupies a small space inside the seat. It is to ensure that it can be used on seats with and without armrests.

Another aim of the invention is to find a seat on the seat thanks to its internal mechanical arrangement. Another object of the invention is the absence of a free play gap. It is to prevent the mechanism from running idle and thus to react immediately to the given effect. to enable it to show.

Another object of the invention is to provide the user with an infinite cascade of adjustment possibilities. is to provide.

In order to fulfill the above-described purposes, the vehicle seats must be fitted to the lumbar region. Allows the user to adjust the seat lumbar support accordingly to provide support. It is an adjustment mechanism for a back support that provides; mechanism together an inner surface and an outer surface, which are interlocked and connected to each other, by stretching or loosening the chassis in the lumbar support area of the vehicle seat. At least one drawstring structure inner surface of the drawstring structure (1) to allow adjustment of the lumbar support and at least one ball at the end to be connected to the outer surface, guide walls in which the balls move by entering and by the user. threaded by the movement of the balls, the rotation of which moves the balls within the guide walls a device that allows the structure to relax and stretch so that the back support can be adjusted. an adjuster with a rotating shaft.

The structural and characteristic features and all advantages of the invention are given in the following figures and It is clearer thanks to the detailed explanation written by making references to these figures. will be understood as such, and therefore the assessment will also include these figures and should be taken into account.

Ball Detailed Description of the Invention In this detailed description, the preference of the adjustment mechanism for the back support, which is the subject of the invention, is explained. structuring, only for a better understanding of the subject is explained.

The invention is designed to provide support to the lumbar region of the user in vehicle seats. adjustment for a back support that allows it to adjust the support to itself mechanism. In its most basic form; interlocking, which keeps that mechanism together a connecting inner surface (1) and an outer surface (2), . located in the chassis (A) of the lumbar support area of the vehicle seat, or at least once to loosen to allow adjustment of the lumbar support. drawstring (4), o located at the end of the threaded structure (4) to be connected to the inner surface (1) and the outer surface (2). at least one ball (5), o It moves by entering the balls (5) at the end of the rope structure (4). guide walls (3.1) and 0 balls to be rotated by the user (5) guide walls (3.1) of the rope structure (4) with the movement of the balls (4), which move it in loosen and stretch so that the back support can be adjusted. a rotating shaft (3.2) that provides contains an adjuster (3). The invention in the disassembled view given in Figure 1 All the elements of the adjustment mechanism in question are seen in detail.

In Figure 2, views of the invention from various angles are given. In Figure 3, the setting The whole view of the mechanism with the seat chassis (A) is given. Adjustment the inner surface of the mechanism (1). outer surface (2) and adjuster (3) plastic injection can be produced with

In a preferred embodiment of the invention, the guide walls (3.1) comprising the adjuster (3) in spiral form. The detail view of the adjuster is given in Figure 6. Adjuster (3) guiding the movement of the balls (5) connected to the rope structure (4) with the guide walls (3.1) it contains is doing. Spiral-shaped guide walls (3.1) both with their geometric structure and With its design that is resistant to the pressure force and friction to be applied by the ball (5) distinguishes the invention from the existing technique.

The working principle in an exemplary vaping of the invention is as follows: Drawstring structure to provide lumbar support in the chassis (A) on the back of the vehicle seat (4) are available. These rope structures (4) are also known as Bowden cables in the art. drawstring There are balls (5) at the end of the structure. Rotation in the adjuster (4) By turning the spindle (3.2), the rope structure (4) is stretched or loosened.

Guide walls (3.1) in spiral form are developed in the adjuster (3). Balls (5) guide it moves spirally by hitting the walls (3.1) and as a result of this rotation, the rope structure (4) increases lumbar support by stretching. When turned in the opposite direction, the threaded structure (4) loosens and lumbar support decreases. The adjuster (3) remains stationary and the ball (5) The turning shaft (3.2) is inside the guide walls (3.1) to keep it within the guide walls (3.1). It enters through the hole (1.1) on the surface (1) and then the inner surface (1) and the outer surface (2). are linked to each other. After connecting the adjustment mechanism to the seat Then the threaded structure (4) and the balls (5) at the end are placed on the adjustment mechanism and adjustment mechanism is ready for use.

The invention is not only used in vehicle seats with armrests, but also in seats without armrests. it is convenient.

The invention is in alternative embodiments. change according to seat structure and place of use can show. Shown in figure 1, depending on whether the vehicle has armrests or not. The change is shown whether the length of the turning shaft (3.2) is long or short.

When the swivel shaft (3.2) is long, it is used on seats with armrests, If the shaft length is short, the lumbar support systems of the seats without armrests and can be used in lumbars.
