Description

Adjustable waist is by

Technical Field

The utility model belongs to the technical field of furniture for daily use, concretely relates to adjustable waist leans on.

Background

The waist supports on the market are various, and have some practical application problems or defects.

Such as: the waist support has the advantages that the waist support is a double waist support with the bulletin number of CN205457449U, the waist support is a self-adaptive adjustment ergonomic waist support with the bulletin number of CN207270149U, the two waist supports are of a two-flap structure, when a person needs to twist, the middle parts of the left and right blades are in contact with the body to generate friction, so that uncomfortable feeling is brought to people, in addition, the middle parts of the left and right blades also bring uncomfortable feeling to the body when the person sits down or rises up, the contact area between the left and right blades and the body of the person is the smallest when the person just sits down or rises up and finally leaves the middle parts of the left and right blades, but the spring force is the largest, the uncomfortable feeling is also the strongest, and if the uncomfortable feeling caused by the friction is overcome, the spring acting force is reduced, so that the body of the person cannot be supported or the sitting posture of the person is ensured.

Such as: the publication No. CN208957323U is a waist support and waist support mounting structure adaptive to human sitting posture, the back of the waist support is mainly supported by an elastic connecting piece with a small area, and the upper part of the waist support body is basically suspended, so the elastic connecting piece is easy to be damaged, and secondly, when a person sits on the back of the waist support body, the unit area of the middle connecting part at the back of the waist support body is also greatly stressed, so the service life of the waist support body is shortened.

Such as: the rocking chair waist support has the publication number CN207506243U, the publication number CN207186390U is a liftable waist support, the middle of the rocking chair waist support is connected by adopting a transverse connecting piece, only the middle left and right supporting points are the same as the CN208957323U, the upper part of the rocking chair waist support is basically suspended, and when a person leans backwards, the rear part of the rocking chair waist support is not provided with a supporting device, so that the connecting piece is easy to damage, and the waist support is damaged.

For comfort, people design the chair back into a shape similar to the curve of the spine of a human body, but the length of the spine of each person is different from the radian of the curve, so that if a backrest or a waist rest cannot be adjusted, the chair back can hardly support the backs, particularly the waist, of different people. At present, a lumbar support is available in the market, as shown in fig. 12, the periphery of the lumbar support is composed of an elastic metal frame, mesh cloth is fixed around the elastic metal frame, two vertical braces are arranged on the back surface of the lumbar support to connect and fix the upper end and the lower end of the elastic metal frame, so that the effect of keeping the C-shape formed on the two sides of the elastic metal frame from deforming is achieved, and meanwhile, an elastic band is generally arranged on the back surface of the lumbar support and used for fixing the lumbar support on the backrest of a common chair. The waist support features ventilation of the user's back and some support for the waist, but there are several problems: the first problem is that the C-shape formed by the waist support depends on two vertical braces at the back of the waist support to play the role of maintaining the shape, but the two vertical braces cannot be adjusted, so that the formed C-shape cannot be changed, and when people with different heights use the waist support, a part of people feel that the waist support cannot well support the waist of the people; the second problem is that the top of the C-shape of the lumbar support is easy to deform greatly under the action of force and become flat, and although the two vertical braces on the back of the lumbar support play a role in keeping the C-shape formed on the two sides of the elastic metal frame from deforming, they cannot ensure that the mesh on the two sides of the metal frame in the middle moves towards the middle in the opposite direction when the mesh is under force, so that the mesh on the top of the C-shape becomes flat and cannot support the waist well as shown in fig. 13; the third problem is that the length of the elastic band used for fixing the waist rest on the backrest of the common chair cannot be adjusted, because the length of the elastic band is fixed, the elastic range is limited, and the elastic force used for fixing the waist rest is basically proportional to the stretching length of the elastic band, the stretching size of the elastic band is small when the backrest size of some chairs is small, the elastic band can provide small elastic force for fixing the waist rest, and the elastic band can possibly cause the situation that the elastic band cannot be sleeved or even causes the situation that the sewing line is broken when the stretching size is not enough for some chairs with large-size backrests.

The waist support on the market is various and has own advantages, the applicant integrates a plurality of waist supports, and the adjustable waist support is researched for overcoming the technical problems.
