Description

Directional sliding device suitable for seat

Technical Field

The utility model relates to a seat manufacturing and designing field, concretely relates to design of back portion of seat.

Background

A chair is a piece of furniture that is used in a wide variety of daily activities and works, and generally includes a base, a backrest, a support structure, armrests, and the like. For example, chinese patent publication No. CN201620974125.9 discloses a chair, which can be supported by the back, waist, buttocks and armrests during use to improve the comfort of human body.

In the using process of the seat, the supporting and abutting area of the seat and the waist and back of the human body is large, and the position is a main supporting and stressed position, so that the abutting structure of the seat to the waist and back of the human body determines the comfort of the seat to a great extent. In order to enhance the feeling of the waist-back interference, the waist-back of the seat is often designed by using an elastic moving structure.

The elastic moving structure is divided into a rotary type and a direct push type, the rotary type is the waist support seat disclosed in Chinese patent document with publication number CN202210377936.0, the waist support is driven by the elastic component to rotate in the horizontal direction by taking the rotating shaft as the shaft, thereby realizing dynamic conflict to the waist and the back of a human body. However, the seat is complicated in structure and high in cost. The direct-push type lumbar support seat has a simple structure and low cost, and for example, chinese patent document CN201621312965.5 discloses an automatic telescopic lumbar support structure for a seat, wherein a spring is connected between a lumbar support and a backrest, and the spring extends in a horizontal direction, so that the lumbar support is driven by the elastic force of the spring to extend forwards to be closely attached to the lumbar of a human body.

However, the design of the direct-push type lumbar-back collision has certain technical defects that the compression and release of the spring are relatively free in the traveling direction, and the lumbar support moves laterally and vertically in the process of moving forwards and backwards. On one hand, the displacement causes the elastic performance to be not uniform enough, and the elastic feedback experience of the user is not good, and on the other hand, the deviation of the displacement also reduces the service life of each component.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The specific embodiments are only for explaining the present invention, and it is not a limitation to the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1, a directional sliding device for a seat comprises a seat frame 4, wherein the seat frame 4 shows a stationary part, which may be a bracket of the seat or a main backrest installed on the bracket. The slide base 3 is mounted on the chair frame 4 in a fixed manner in this embodiment, and there is no relative movement between the two.

The board mount 1 is slidably mounted on the slide base 3 as a slide member in a horizontal front-rear direction. In the present specification, the front-back direction means: the direction close to the waist and the back of the human body and the direction far away from the chair frame 4 are front; the direction far away from the waist and the back of the human body and the direction close to the chair frame 4 are the back. The chaser 2 is mounted on the front section of the board mount 1. (only a portion of the structure is shown in figure 1 for the backing member 2, other structures are not shown.)

And the gliding driving force of board mount pad 1 comes from the elasticity of main elastic component 6, and it is installed in the inner chamber that comprises sliding base 3 and board mount pad 1 jointly, and both ends are contradicted with base 3 and board mount pad 1 respectively. The main elastic member 6 can be an elastic member commonly used in the prior art, such as an elastic column, a spring, etc., and in this embodiment, a spring is taken as an example. The spring provides an outward spring force to the board mount 1, so that the body-tracing member 2 is attached to the back of the human body at all times. When the waist of the human body leans back, the plate mounting seat 1 moves backwards, and the spring is compressed.

In the scheme, the sliding track of the plate mounting seat 1 in the front-back direction is strictly limited and is limited to be a straight track, so that on one hand, the action track of the back-chasing piece 2 is accurate, the collision on the waist and the back of a human body is not deviated, and the collision effect is good; on the other hand, the side direction or the up-and-down displacement of each part when moving back and forth is avoided, the damage and the folding are avoided, and the service life of the parts is optimized.

The design of 'double limiting of a strip channel pin slot' is adopted in the scheme. Specifically, the side walls of the two ends of the seat body 11 are provided with inward concave main slideways 17, and the side wall of the sliding base 3 comprises inward and outward convex guide strips 31. The guide strip 31 and the main runner 17 are fitted to each other in shape and size, and extend in the horizontal front-rear direction. The positioning pins 5 are fixedly mounted on the seat body 11, and the guide bar 31 is provided with pin grooves 311 which also extend in the horizontal front-rear direction, and the positioning pins 5 slide in the pin grooves 311. So far, the cooperation of the guide strip 31 and the main slideway 17 and the cooperation of the positioning pin 5 and the pin slot 311 play a role of stable front and back guiding and limiting for the movement of the back-tracking piece 2.

As shown in fig. 3, an inwardly protruding recessed reinforcing body 113 is provided in the inner cavity of the seat body 11 at a portion of the main chute 17. This is because locating pin 5 is a direction atress piece of slip process, if too thin with main slide 17, not only the atress is unstable easily destroys, and can regard as a line contact between main slide 17 and the locating pin 5 approximately, makes locating pin 5 overturn in vertical direction easily, and the precision of direction can receive certain influence. And the structural strength of the connection position is enhanced by the invagination reinforcement body 113, more importantly, the contact area with the positioning pin 5 is increased, the original line contact is changed into surface contact, the positioning stability of the positioning pin 5 is stronger, and the pin is not easy to turn over.

As shown in fig. 1 and 2, an auxiliary slide way 18 is provided on the upper surface of the seat body 11, and an auxiliary strip 32 is provided on the upper surface of the slide base 3 to be matched therewith, and both extend in the horizontal front-rear direction to perform the function of auxiliary guiding and positioning. And chair frame 4 includes a plurality of cassette arriss 41, blocks in the surface of sliding base 3 for sliding base 3 this motionless spare is more stable, further guarantees the precision of slide guiding.

A plurality of micro-contact ridges 34 are protruded on the inner surface of the slide base 3, the micro-contact ridges 34 are distributed over a plurality of surfaces, and the individual micro-contact ridges 34 have a small volume and extend in the horizontal front-rear direction. It has two design considerations: on one hand, the auxiliary function of front and back guiding is also achieved, on the other hand, the contact area between the seat body 11 and the sliding base 3 in the sliding process is prevented from being too large, and the micro-contact edges 34 enable the seat body 11 to move back and forth more smoothly

As shown in fig. 2 and 3, one end of the spring is mounted in the retaining ring 33, and the other end is sleeved on the linear column 111. A buffer sleeve (not shown) is arranged on the outer side of the spring, and an arc-shaped attaching edge 112 is arranged at the corresponding position of the seat body 11 and has the size matched with the buffer sleeve. In the process of spring extension and compression, the cushion collar and the linear column 111 provide linear guide for the spring, and the arc attaching edge 112 also provides guide and attaching support, so that the directional stability of the spring force is further improved.
