Description

The seat waist is by package assembly

The utility model relates to a kind of seat waist by package assembly, mainly refers to a kind of simple and convenient assembly, and can the person's of being used demand adjust the waist rest cushion position to promote driving comfort and applicability.

Existing seat generally is provided with the pad portion of protruding at the chair back near occupant's waist location for promoting riding comfort, and supports occupant's waist to alleviate lumbar fatigue by this pad portion.

Existing seat generally can not be adjusted by the portion position at the waist of chair back setting, and this waist rest cushion portion correct surely closing occupant waist that differs forms and takes uncomfortable and the not good shortcoming of applicability when causing the different users to take.

The purpose of this utility model is to realize a kind of seat waist of assembling facility, preferable applicability by package assembly, and can make waist by the adjustment of the person's of being used height, has comfortableness.

To achieve these goals, the utility model is taked following design: this seat waist is by package assembly, this package assembly comprises the chair back, adjusts seat, junction piece, waist lean on make up, and these chair back central authorities have elastic pad, and install joining hole at the corresponding occupant's back of two side skeletons; Described again adjust seat be a side setting can for joint fastener, the conjugate foramen of chair back skeleton combination, and the vertical setting of joint fastener can for and the winding sheet of waist by making up, and the strip slotted eye is set at the winding sheet, and in slotted eye, set described junction piece, and can be for the perforation that interts bolt in the setting of junction piece central authorities with suitable tightness by adjusting the flexible of seat; Described again waist is formed by comprising support chip and cushion, and this support chip two side settings can for and adjust the junction surface of seat combination, and be provided with at the junction surface can for the joining hole of aforementioned screw threaded, and set firmly cushion in support chip the place ahead; It is affixed by joint element and chair back skeleton to adjust seat, and waist by by the joining hole winding at interspersed junction piece of bolt and junction surface so that waist be located on the chair back by group.User's application of force on demand makes junction piece along the slotted eye displacement of adjusting seat, and closes junction piece by the flexible clip of slotted eye and lean on suitable height and position with the location waist.

In the utility model, the inboard setting of described joint fastener can be for the joint surface of location waist by deviation angle, and the corresponding aforementioned joint surface of the support chip junction surface one side position leaned on of waist is provided with and can limits the abutment face of waist by deviation angle again.Waist is leaned on the person of being used to take the posture skew, and can lie by supportive and stability with enhancement by abutment face and joint surface closing

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 makes up schematic diagram for embodiment of the present utility model

Fig. 3 is embodiment of the present utility model and chair configuration schematic diagram

Fig. 4 analyses and observe for embodiment of the present utility model combination and adjusts schematic diagram

Fig. 5 analyses and observe for embodiment of the present utility model combination and waist moves schematic diagram by skew

As shown in Figure 1, the utility model mainly by the chair back 1, adjust seat 2, junction piece 3, waist by 4 combinations, and this chair back 1 is that central authorities have elastic pad 11, and at two side skeletons, 12 corresponding occupant's waist locations joining hole 13 is set;

Adjust seat 2 again and be a side setting can for joint fastener 21, the conjugate foramen 22 of the chair back 1 skeleton 12 combinations, and can be for the joint surface 23 of location waist by 4 deviation angles in joint fastener 21 inboard settings, again can be for leaning on the winding sheets 24 of 4 combinations with waist in joint fastener 21 vertical settings, and the equidistant slotted eye 25 of strip is set at winding sheet 24, and in slotted eye 25, set junction piece 3, and can be for the perforation 31 that interts bolt 32 in junction piece 3 central settings with suitable tightness by adjusting the flexible of seat 2;

Waist comprises that by 4 support chip 41 and cushion 42 form, and this support chip 41 is can supply and junction surfaces 411 of adjusting seat 2 combinations in two side settings, and at the junction surface 411 be provided with can be for the joining hole 412 that screws togather with aforementioned bolt 32, and the corresponding aforementioned joint surface of 411 1 sides 23 positions are provided with and can set firmly cushion 42 in support chip 41 the place aheads again for the abutment face 413 of restriction waist by 4 deviation angles, 1 degree at the junction surface.

During combination such as Fig. 2, shown in Figure 3, wherein adjusting seat 2 can be affixed by joint element and the chair back 1 skeleton 12, and waist can intert joining hole 412 windings at hole 31 and junction surface 411 of junction pieces 3 so that waist leans on 4 can organize and be located on the chair back 1 by bolt 32 by 4.

As shown in Figure 4, user's application of force on demand makes junction piece 3 along slotted eye 25 displacements of adjusting seat 2, and by the flexible clip of slotted eye 25 close junction piece 3 with the location waist by 4 suitable height and positions, make the utility model can have a preferable applicability.

As shown in Figure 5, when the user takes, this waist can the person's of being used waist be lain by 4 and is lain by supporting comfortableness with enhancement by the direction skew, and can by waist by 4 abutment face 413 with adjust a joint surface 23 of 2 against preventing that waist from leaning on 4 over-deflection, and can promote stability of strutting system.

By the above, when the utility model structure is implemented, be to make waist lean on to assemble with the chair back easily, can have and assemble convenience, and the position that is provided with that makes that waist leans on can the adjustment of the person's of being used height, can have preferable applicability, and waist is by can the person of being used taking stance adjustment support direction, and can be by abutment face and joint surface against to prevent that waist from leaning on over-deflection, make and to have preferable support comfortableness and stability, and the open or application of product is not arranged roughly the same formerly because of seeing, utility application is proposed in accordance with the law.
