Description

Elastic self-adaptive supported waist support

Technical Field

The utility model relates to an automobile seat component, in particular to an elastic self-adaptive supporting waist support.

Background

With the development of automobile science and technology, the requirement of consumers on the riding comfort of automobile seats is higher and higher, and an important standard for evaluating the comfort of the seats is whether the driving fatigue can be effectively relieved.

In the early structure of the seat, only the seat cushion and the backrest are usually included, the seat cushion is supported by the seat basin, and the backrest is supported by the backrest framework, so that the support performance of the seat structure on the human body is not fully considered, the waist of the human body is in a suspension posture, and the driver and passengers are easy to feel tired in the waist after sitting for a long time.

Therefore, a lumbar support technology applied to a seat also comes up, namely a so-called lumbar support, the lumbar support relieves the lumbar fatigue of drivers and passengers due to the suspension of the waist to a certain extent, and in the prior art, no matter the lumbar support is a fixed lumbar support or an adjustable lumbar support, the lumbar support is completely fixed relative to a backrest in the process of supporting the waist of a user and cannot float adaptively along with the self weight of the human body, so that the comfort is poor.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an elastic self-adaptive supported lumbar support to solve the technical problem of poor comfort of the existing lumbar support.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

the utility model provides a waist that elasticity self-adaptation supported holds in palm, includes the back framework and is located the inside supporter of back framework, and its main points lie in: the upper end of the support body can rotate relative to the backrest frame body, the lower end of the support body is connected with a pull rope, the pull rope is transversely arranged along the width direction of the support body, a first hanging piece and a second hanging piece are arranged at two ends of the width direction of the backrest frame body respectively, and two ends of the pull rope are respectively hung on the first hanging piece and the second hanging piece through a first spring and a second spring.

With the above structure, the lower end of the support body is suspended and supported in the backrest frame body by the first spring and the second spring, and the upper end of the support body can rotate relative to the backrest frame body, so that when the waist of a user is supported on the support body, the support body can float adaptively along with the thrust or dead weight of the back of the human body, thereby forming an elastic support and having more excellent comfort.

Preferably, the method comprises the following steps: the pull cable is characterized in that a movable guide sleeve and a fixed guide sleeve are slidably sleeved on the pull cable, the movable guide sleeve is hung at one end, away from the first hanging piece, of the first spring, the fixed guide sleeve is fixedly assembled at the lower end of the supporting body, a pull cable motor is installed on the side portion of the backrest frame body, and the pull cable motor is connected to one end, close to the movable guide sleeve, of the pull cable. By adopting the structure, the stay cable motor can drive the support body to move, thereby realizing the adjustment of the waist support in the thickness direction of the backrest.

Preferably, the method comprises the following steps: and one end of the inhaul cable far away from the inhaul cable motor is hung on the second spring.

Preferably, the method comprises the following steps: the middle part of the backrest frame body is transversely provided with a spring steel wire, and the upper end of the support body is rotatably hung on the spring steel wire. By adopting the structure, the spring steel wire can also provide certain elastic supporting force, which is helpful for further improving the comfort.

Preferably, the method comprises the following steps: the number of the fixed guide sleeves is two, and the fixed guide sleeves are symmetrically distributed at the lower end of the support body. By adopting the structure, the reliability of the installation of the inhaul cable can be ensured.

Preferably, the method comprises the following steps: a first straight line hole and a second straight line hole which are perpendicular to each other are formed in the movable guide sleeve, and an arc-shaped hole is connected between the first straight line hole and the second straight line hole in a transition mode. Adopt above-mentioned structure, can help the cable to change from vertical to horizontal.

Compared with the prior art, the utility model has the beneficial effects that:

by adopting the elastic self-adaptive support waist support provided by the utility model, when the waist of a user is supported on the waist support, the support body can adaptively float along with the thrust or dead weight of the back of the human body, so that an elastic support is formed, and the support is better in comfort compared with the traditional waist support structure.

Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 to 3, an elastic self-adaptive supported lumbar support comprises a backrest frame 1 and a support body 2 located inside the backrest frame 1, wherein the support body 2 is a main body part of the lumbar support, a spring steel wire 11 is transversely arranged in the middle of the backrest frame 1, a hanging groove 2a is arranged at the upper end of the support body 2, the support body 2 is rotatably hung on the spring steel wire 11 through the hanging groove 2a, a cable motor 10 is installed at the side part of the backrest frame 1, the cable motor 10 is connected with a cable 3, one end of the cable 3 far away from the cable motor 10 is installed at the lower end of the support body 2 and transversely arranged along the width direction of the support body 2, the positions of the cable 3 corresponding to the two ends of the support body 2 in the width direction are respectively hung on the backrest frame 1 through a first spring 6 and a second spring 7, when the user lumbar is supported on the support body 2, the cable 3 plays a bearing role and can support the user lumbar, due to the arrangement of the first spring 6 and the second spring 7, when the back of a human body is thrust or dead weight is borne, the supporting body 2 can float adaptively, and the comfort is better.
