Description

Seat with flexible lumbar support

The present invention relates to an accessory on a seat, particularly a seat having a flexible lumbar support. Before the present invention Ϊ!»有技术

The supporting lumbar seat of the existing seat mostly fixes a horizontally convex lumbar support in the waist region of the seat, and the human body must lean back to a horizontal angle of more than 90° to obtain the supporting force of the support forward. Because the support member is installed in the seat back and integrated with the seat, the support member in the seat back can only move up and down for the height position of the human waist, and cannot move horizontally, and the human body stands vertically or slightly forward. When leaning, the waist can not get support, and feels tired; the human body is standing upright for a long time and brings health hazard to the back, especially the waist.

Purpose of the invention

In view of the above problems of the prior art, an object of the present invention is to provide a flexible lumbar support member which independently supports a human waist on a seat and enables the waist of the human body to be supported whether standing upright, reclining or slightly leaning forward. Seat.

Technical solution adopted by the invention

The method of the present invention comprises a seat having a seat, a seat back, an armrest and a base assembly, characterized in that: a flexible support member having a toughness is connected to the seat, and the flexible support member is available in the seat. The waist area moves in the horizontal direction.

The flexible support member described above is a strip-shaped, strip-shaped, rope-like product, and the flexible support member is connected to the armrest of the seat, and is made in the waist region by a slip device provided on the armrest. Move horizontally.

The flexible support member described above and the sliding device of the armrest are movably connected or fixedly coupled.

The flexible support member of the present invention comprises a flexible member. The middle portion of the flexible member is a soft body, and the top ends of the two ends are respectively connected with positioning buckles through pivots, and the pivot shafts are slidable along the sliding devices on the armrests on both sides.

The sliding device provided on the armrest is composed of a slide rail and a positioning groove, and the flexible member can be horizontally slid along the downwardly extending arcuate slide or fixed in the positioning groove by a locking buckle on the positioning groove. Self-locking status.

The positioning buckle at the top of both ends of the flexible member can be engaged in the positioning groove, and the pivot of the rear end of the positioning buckle can slide along the slide.

The top ends of the flexible support members are suspended by the self-weight of the soft body, and the positioning buckle is disengaged from the positioning groove, so that the flexible support member slides down the slide rail to the end of the handrail to form an automatic reset.

The above-mentioned flexible support member can be placed in a collection slot provided on the seat after being automatically reset.

The soft outer surface is covered with a cushion composed of a coated sponge such as cloth or leather, and the flexible body may be built in or jacketed with a massage bump.

The invention provides a seat with a flexible lumbar support, which has the advantages of simple structure and convenient operation, and is characterized in that: the seat is provided with an independent flexible lumbar support member which is movable in the horizontal direction in the waist region to make the waist of the human body The support of the waist is available at any position of the seat, reducing the load on the waist and automatically resetting it when not in use.

When the flexible support is connected to the armrest in the form of strips, strips, or rope-like flexible members, By pressing against the soft body on the flexible member, the soft body has a pressing effect on the back of the sitting person, so that the compression of the spine, muscles and nerves of the back and back of the person is improved.

The soft body according to the present invention refers to a flexible product such as a strip shape, a belt shape, a rope shape, etc., and when the soft body is in contact with the human body, it can conform to the human body according to different shapes of the human body, and serves as a support.

Example 1

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, the seat 1 of the present invention has a seat 6, a back 2, an armrest 5, a base assembly 7; a flexible support member 3 and a slip device 4 built in the armrest 5 Engaging each other and moving horizontally in the waist region of the seat 1 by the slip device 4;

The flexible support member 3 comprises a flexible cord-like flexible member with a soft body 31 in the middle, and a pivot shaft 32 and a positioning buckle 33 are respectively connected at the ends thereof;

The sliding device 4 is built in the armrest 5. The sliding device 4 includes a slide 41 extending downwardly in an arc. The slide 41 is provided with at least three positioning slots 42. The positioning buckle 33 on the flexible support 3 can be The card is combined and fixed on the positioning slot 42.

3

Correction page (Article 91) The flexible support member 3 slides down on the end of the armrest 5 by gravity, and can be stored in the gap between the seat 6 and the seat back 2, without affecting the appearance of the seat, while the flexible support member 3 has no axial force acting on the waist. Then, it will slide down to the end of the slide along the slide 41 on the slip device 4 according to its own gravity, that is, an automatic reset is formed.

Example 2

As shown in Fig. 5, before use, the flexible support member 3 is placed at the end of the armrest 5 due to gravity. When it is needed, the seater leans back in the sitting position, and pulls the flexible support member 3 to make it close to the waist and then pass the flexibility. The positioning buckle 33 on the support member 3 and the positioning groove 42 in the sliding device 4 on the armrest are clamped and fixed to each other. At this time, the soft body 31 is in close contact with the waist portion, and the soft body 31 can be sufficiently supported when the human body is reclined.

When the occupant does not need to use the flexible support member 3, the waist portion can be separated from the flexible support member 3. When the flexible member is weakened, the flexible support member 3 is automatically detached by gravity under the action of gravity. The groove 42 is positioned and slides along the slide 41 to the end of the slide, that is, it slides down to the end of the armrest 5 to be hidden, forming an automatic reset state (ie, an original state), thereby ensuring the original appearance state of the seat.

Example 3

As shown in Fig. 6, in the present invention, when the seated person is standing upright and the waist portion is desired to be supported, the flexible support member 3 can be pulled up and moved along the slide 41 on the slip device 4 to the desired waist position at the positioning groove 42. The inner body is fixed, and the soft body 31 is a force for pressing the waist of the human body forward, and the human body also generates a force for pressing backward. The soft body 31 is slightly bent backward according to the waist of the human body under the force, and the top pressure is followed. When the human body is increased, the support force of the waist can be obtained, and the compression condition of the spine, muscles and nerves of the lower back of the occupant is improved; The formula and effect are basically the same as in the second embodiment.

Example 4

As shown in FIG. 7, the present invention can also be applied to a person who is used when leaning forward slightly. When the sitting posture is slightly tilted forward, the flexible support member 3 is pulled up to be in close contact with the waist, and the waist portion can obtain the supporting force. The weight that the waist receives is reduced; the embodiment and effect of the present invention are basically the same as those of the second embodiment.

Since the flexible support member is connected to the armrest, the flexible support member can be adjusted by the lifting of the armrest according to the height of the user's waist so that the flexible support member can be in close contact with the waist of the human body.

The flexible support member of the present invention can be combined with a seat, a seat back, and a base assembly on the seat to form a lumbar support.
