Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on a general office seat (chair) or an automobile seat, and can be adjusted in height according to the waist position of the occupant, so that the occupant's waist is in a comfortable posture. The present invention relates to a seat rest waist that can be brought into a state.

[0002]

2. Description of the Related Art A conventional waist rest for placing a seat on a seat is configured such that a decorative bag made of fabric or the like is filled with an elastic member (urethane foam) so as to have a fixed width, height and thickness. (Not shown). In use, the waist rest is placed on the joint corner between the seat portion and the backrest, where the waist portion of the seated person does not directly contact. In other words, the waist support is used while standing in contact with the seat backrest surface.

[0003]

A conventional waist pad, for example, is merely a cloth bag filled with urethane foam, and has no adjustment member for adjusting the mounting height of the waist pad. By the way, the sitting height of the seated person varies. For this reason, for example, there is a disadvantage that a low-seat occupant can fit the waist, but a high-seat occupant cannot fit the waist properly. In addition, since the conventional backrest is simply placed on the seat back surface, it is not a disadvantage that the backrest falls down from the seat back surface every time a occupant gets on and off the vehicle. Had disadvantages such as the movement of the waist pad.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and makes it possible to adjust the height of the waist rest body so that it can be fitted to the waist of occupants of various sitting heights. It is an object of the present invention to provide a seat rest waist that does not move or fall down.

[0005]

In order to achieve this object, a seat rest waist according to the present invention comprises:
It has the following configuration. The waist rest for seat rest is placed on the seat backrest surface in a face-to-face manner, and a waist rest body in contact with the waist of the seat occupant, and one end is attached to an appropriate position of the waist rest body, and It is characterized by comprising a pair of height position adjusting members whose ends are coupled on the back side of the seat.

The seat rest waist having such a configuration is placed at the joint corner between the seat portion and the backrest, that is, in the space between the waist portion of the seat occupant and the lower portion of the backrest. For example, if the seat is the front seat of a car,
After placing the waist rest body at the joint corner of the seat and backrest,
Two pairs of height position adjusting members (tape-shaped cords) are circulated around the back of the seat headrest so as to face each other, and the front ends of the two tape-shaped cords are joined at the back of the headrest to form a backrest surface of the waist body. Adjust the height position with respect to. The sitting height of the occupant varies. Therefore, the degree of coupling of the two tape-shaped cords is adjusted so that the waist rest body is in contact with the waist of the occupant. That is, the height of the waist pad main body is maintained at an appropriate position by adjusting the length of the circumference where the two tape-shaped cords are joined. Thereby, the waist rest body can be appropriately made to correspond to the waist part of the occupant having various sitting heights. In addition, the waist rest body is fixed to the seat headrest in a suspended manner by the height position adjusting member, so that not only undesired falling down but also movement is prevented and stable positioning is achieved.

[0007]

In this embodiment, an example is shown in which the seat 4 is a front seat of an automobile. The seat rest waist rest is placed on the seat backrest surface in a face-to-face manner, and a waist rest body 1 facing the waist of a seat occupant, and one end is attached to an appropriate position of the waist rest body 1. And a pair of height position adjusting members 2 whose other ends are coupled on the back side of the seat headrest 42.

The waist pad main body 1 shown in FIG. 2 comprises a frame portion 11 using a round bar-shaped metal material and a mesh portion 12 stretched in the plane of the frame portion 11. The mesh portion 12 may be a fabric sheet or a sheet made of a synthetic resin sheet provided with a large number of air-permeable holes, or may be a mesh sheet in which various fiber yarns are knitted. The frame 11 of the waist rest body 1
The central portion is curved in a bow shape, and both right and left sides are bent and set so as to project forward with respect to the central portion. The mesh portion 12 is stretched on the frame portion 11 so as to have elasticity. I have. An edge cloth 11a that embraces the outer edge of the mesh portion 12 is sewn to the outer edge of the waist pad main body 1 for reinforcement.

FIG. 1 is a perspective view showing another embodiment of the waist pad main body 1. The waist rest body 1 of this embodiment is
A press bead portion 13 which has the same configuration as that of the above-mentioned waist pad main body (the waist pad main body shown in FIG. 2) 1 and is provided at the center in the plane of the mesh portion 12 and is arranged in a superimposed manner on the mesh portion 12. It is a thing. The pressing bead portion 13 includes a small-diameter bead 13a, a medium-diameter bead 13b, and a large-diameter bead 13c.
Are connected to each other by a passing thread. The pressing bead portion 13 is framed by small-diameter beads 13a arranged in the vertical and horizontal directions, and a plurality of medium-diameter beads 13b are arranged in the vertical direction on the left and right sides of the vertical center in the plane of the frame. A plurality of large-diameter beads 13c are arranged outside the large-diameter beads 13b in the vertical direction. As a result, both the medium-diameter beads 13b and the large-diameter beads 13c press the acupoints called "pots" located on the left and right sides of the waist longitudinal center against the curved waist of the seat occupant, and exert the acupressure effect. I do.

The pair of height adjusting members 2 comprises non-stretchable narrow tape-shaped cords 2a and 2b such as non-stretchable leather, cloth, and synthetic resin tape strings. It is arranged on the back side of and is pulled out upward and outward. FIG.
FIG. 4 is an explanatory view showing a height position adjusting member 2. Two non-stretchable narrow tape-shaped cords 2 constituting the height position adjusting member 2
In a and 2b, one end 21 is sewn to the center of the length of the chordal string 14 attached to the back side of the waist rest body 1. Then, the other end 22 of the narrow tape-shaped cord is set as a free end, and is pulled upward and outward. The chordal cords 14, 14 arranged on the back surface of the waist rest body 1 are non-stretchable tape-like cords, and upper and lower ends 14 a and 14 b of the cords are respectively wrapped around the upper side and the lower side of the frame 11. It is sewn in the state and stretched. When the waist rest body 1 is placed on the seat backrest 41, the straight chordal cords 14, 14 are in contact with the backrest 41 surface, and the waist rest body is caused by the reaction force of the load applied to the waist rest body 1. Reinforce the elasticity of 1.

FIG. 4 is an explanatory view showing another embodiment of the height position adjusting member 2. As shown in FIG. In this embodiment, the frame 1

One end 21 of a pair of narrow tape-shaped cords 2a, 2b constituting the height position adjusting member 2 is sewn around the upper side of the frame portion 14, and the other end 22, which is a free end, is pulled out upward and outward. I have.

FIG. 5 is an explanatory view showing still another embodiment of the height position adjusting member 2. As shown in FIG. In this embodiment, only the lower end portion 14b of the chordal string 14 is sewn around the frame portion 11 to make the upper end portion 14a a free end, and a buckle portion 14c is provided at the tip end of the upper end portion 14a. The two narrow tape-shaped cords 2 a and 2 b are sewn around one end 21 on the upper side of the frame 11, and the other end 22, which is a free end, is a buckle 14.
c, and is locked by being inserted through the other end 22.
a is drawn upward and outward.

A buckle 14c is attached to the upper end (tip end) 14a of the chordal cord 14, and the other end 22 of the tape-like cord is inserted through the buckle 14c. Will be pulled upward and outward. Further, in this embodiment, a part (lower part) of the narrow tape-shaped cord 2a (2b) forms a part of the chord-shaped cord 14 with the tip of the upper end part 14a inserted through the buckle part 14c. It will be shared. Therefore, in this case, the tape-shaped cord 2a (2b) can exert the elastic reinforcement effect (the chord-shaped cord 14 effect) of the waist rest body 1 in addition to the height position adjusting function.

FIG. 6 shows an example in which an engaging portion 23 and an engaging receiving portion 24 are attached to the distal ends of the narrow tape-shaped cords 2a and 2b constituting the height position adjusting member 2. A band fitting (clasp) 23 is provided at the distal end of one narrow tape-shaped cord 2a, and is engaged with a latch (engaging portion) 23 in the surface of the other narrow tape-shaped cord 2b on the distal end side. A plurality of holes 24 for possible engagement
The engagement receiving portion 24 made of a is provided. Engagement receiving part 2
By selecting the four holes 24a arranged in tandem and engaging with the band fitting 23, the orbital length of the two narrow tape-shaped cords 2a and 2b is adjusted.

A brushed cloth made of a group of loop-shaped fibers is attached to the tip of the other tape-shaped cord 2b, and a position where both narrow tape-shaped cords 2a and 2b are overlapped and locked is selected.
Adjust the orbital length of a and 2b.

Although not shown, a sheet-like magnet is attached to the tip of one tape-like cord 2a instead of a hook-and-loop fastener as an engaging means, and a sheet-like metal is attached to the tip of the other tape-like cord 2b. A (sheet-like iron plate) may be provided to select the position where the two tape-shaped cords 2a and 2b are overlapped and adsorbed.

The seat rest waist having the above structure is mounted on the seat 4 as follows. FIG.
As shown in FIGS. 1 and 2, the operation when the seat 4 is an automobile seat (front seat) is described. The waist rest body 1 is placed upright on the backrest 41 of the seat 4.
In other words, the seat backrest 41 is placed on the backrest 41 corresponding to the joint corner (the space where the waist does not contact) of the seat back 43. Then, as shown in FIG. 7, the two narrow tape-shaped cords 2a and 2b are pulled out upward, and each of them is made to go around the seat headrest 42. They are tied on the back side to form a joint 2c (see FIG. 7). Alternatively, as shown in FIG. 6, the engaging portions 23 of the narrow tape-shaped cords 2a and 2b and the engaging receiving portions 24 are engaged and locked.

At this time, the tying position (circumferential length of the two tape-shaped cords) 2c of the narrow tape-shaped cords 2a and 2b is adjusted so that the waist of the occupant properly corresponds to the waist rest body 1. I do. Thus, the waist rest body 1 can always be fitted to the proper position with respect to the waist of the occupant having various sitting heights, and the proper position is held and fixed. For example, the waist rest body 1 indicated by a solid line in FIG. 8 indicates a placement position in the case of a seat occupant having a low sitting height, and the hip rest body 1 indicated by a virtual line is positioned at a height corresponding to a seat occupant having a high sitting height. The state where the height position is adjusted by the adjusting member 2 is shown.

In particular, in the case of the waist pad main body 1 in which the pressing bead portion 13 shown in FIG. 1 is arranged in a plane, the height position of the waist pad main body 1 is adjusted by the height position adjusting member 2 so as to be always seated. Medium diameter beads 13b and large diameter beads 13
c can be appropriately positioned along the curved surface of the waist, and the pressing effect by finger pressure can be effectively exerted.

FIG. 9 shows a cushion body having a thickness in which the waist pad main body 1 has a built-in urethane foam. The waist pad main body 1 is provided with two chordal cords 14 shown in FIG. The figure shows two thin tape-shaped cords 2a, 2b) 2 attached. FIG. 9 shows this waist rest body 1 as a general office seat (chair), that is, a backrest 41 and a seat part 4.
3 shows a case where there is a space between the backrest 41 and the height of the backrest 41 is low and the backrest 41 is mounted on an office seat without a headrest.

In this case, the string-like string 14 is pulled out to the upper rear part of the backrest 41 through the space between the backrest 41 and the seat 43, while the narrow tape-like string 2a (2b) is pulled up on the upper surface of the backrest 41. Along the back of this tape-shaped cord 2a (2
The distal end of b) is inserted and locked in the buckle portion 14c at the distal end of the string-like string 14. As a result, the back of the thick waist rest body 1 is brought into contact with the backrest 41, and
The waist rest body 1 is fixed to the backrest 41 in a manner of being wrapped (embracing) by the and the narrow tape-shaped cord 2a (2b).

String string 14 and narrow tape string 2a (2b)
It is needless to say that the height position of the waist rest body 1 can be adjusted by adjusting the orbital length by engagement with the waist. Also, if this backrest 41 has a headrest 42,
Narrow tape-shaped cord 2a inserted and locked in buckle part 14c
The leading end of (2b) is pulled up to the headrest 42, and the leading ends of both tape-shaped cords 2a, 2b are
It is also possible to tie on the back of 2. In this case, the movement of the waist rest body 1 can be reliably prevented.

[0024]

According to the present invention, as described above, a pair of two height positions are provided at appropriate positions on the waist rest body which is placed on the seat backrest surface in a face-to-face manner and faces the waist of the occupant. Since one end of the adjustment member is attached and the other end is joined on the back side of the seat, the other ends of the two height position adjustment members, which are free ends, are rotated around the back of the seat headrest, for example. By joining the revolving tip, the backrest body is fixedly held in contact with the backrest surface, and it is not allowed to eliminate disadvantages such as undesired lodging, etc. To prevent large movement in the left-right direction. In addition, by adjusting the orbital length by coupling the two height position adjusting members, the waist rest body can be made to correspond to an appropriate position of the waist of the occupant. Therefore, the present invention has an excellent effect of achieving the object of the invention, such as being able to always accurately position the waist rest body with respect to occupants of various sitting heights.
