By following corresponding accompanying drawing of reference and detailed description, the advantage that the present invention may be better understood, wherein:
Fig. 1 is the front elevation according to seat assembly of the present invention;
Fig. 2 is the upward view that has comprised the seat assembly that places the cable in cover of upholstery (trim cover) material;
Fig. 3 is the amplification inclinating view that has comprised the seat assembly of stretching unit, and stretching unit has the relative adjusting arm that links to each other with cable; And
Fig. 4 is and the similar amplification inclinating view of Fig. 3 that wherein adjusting arm moves away from each other.
The specific embodiment
With reference to figure 1, be depicted as according to seat assembly of the present invention, represent with 10 on the whole, be used for the occupant in the support machine motor-car (not shown).This seat assembly 10 comprises seat cushion 12 and back of seat 14, and wherein back of seat 14 pivots to be connected to be used for seat assembly 10 with seat cushion 12 and moves between a plurality of seating positions.Alternatively, back of seat 14 can be fixedly installed to seat cushion 12 and makes seat assembly 10 remain on a basic vertical seating position.
With reference to figure 2, trim cover material 30 defines outer peripheral edges 32, and these outer peripheral edges 32 extend across front piece 18 and the back member 20 and the side member 22,24 of seat frame 16 and twine thereon.This trim cover material 30 comprises the cover 34 that extends along the base portion of outer peripheral edges 32.Cover 34 is placed along the basal surface 36 of seat frame 16.Cover 34 comprises cover end 38,40, and the opening 42 at each 38,40 place, end.
Optionally adjust tension force in the trim cover material 30 with 44 stretching devices that indicate on the whole for one.Stretching device 44 comprises the cable 46 that places slidably in the cover 34.Cable 46 is included in the centre portion 48 that extends between the cable and damper ends 50,52.Centre portion 48 places in the cover 34 and along the base portion of the outer peripheral edges 32 of trim cover material 30 and extends.Cable and damper ends 50,52 is stretched out from overlapping 34 opening 42 at 38,40 places, corresponding cover end.Cover 34 outer peripheral edges 32 along trim cover material 30 have a plurality of breaches 51, with the centre portion 48 that allows to cable 46.
With reference to figure 3, stretching device 44 also comprises one on the whole with 54 stretching units that indicate, and it is connected with cable and damper ends 50,52 and is used for tensioning cable 46.In a preferred embodiment, stretching unit 54 can move freely, and for example stretching unit 54 is not fixed to any part of seat assembly 10.But, in order to obtain leverage when the tensioning cable 46, imagination is fixedly attached to stretching unit 54 certain part of seat assembly 10.
Stretching unit 54 has the base portion 56 of extending between first end 58 and the second end 60.Base portion 56 is included in the relative tapped bore 62,64 at corresponding first end 58 and the second end 60 places.Tapped bore 62,64 is aligned axially to each other.
Stretching unit 54 also comprises from the first end 58 of base portion 56 and stretching out with the second end 60 and relative adjusting arm 66,68.Adjusting arm 66,68 includes the screw rod 70 that rotatably engages with the tapped bore 62,64 at the first end 58 of base portion 56 and the second end 60 places.Adjusting arm 66,68 rotations along tension direction make adjusting arm 66,68 shift to base portion 56, and adjusting arm 66,68 makes adjusting arm 66,68 move away from base portion 56 along the rotation of loosening direction.
In the adjusting arm 66,68 each all also comprises and being used for stretching unit 54 and cable and damper ends 50,52 bonded assembly hooks 72.Can functionally connect handle or handle (all not shown) on the hook 72, so that adjusting arm 66,68 is along tension direction with loosen direction and rotate.But, should be appreciated that, be connected with cable and damper ends 50,52 that adjusting arm 66,68 can comprise that any can be connected to stretching unit 54 connecting device of cable and damper ends 50,52 although be illustrated as a hook.
Adjusting arm 66,68 is adjusted the tension force of cable 46 with respect to the rotation of base portion 56 by the whole effective length that changes cable 46, and then adjusts the tension force of trim cover material 30.Specifically, adjusting arm 66,68 rotations along tension direction make adjusting arm 66,68 move towards each other.Adjusting arm 66,68 this moves in opposite directions because cable and damper ends 50,52 is inwardly pulled to base portion 56, thereby shortened the length of cable 46, and increased the tension force of cable 46.Like this, the outer peripheral edges 32 of trim cover material 30 cooperate around seat frame 16 tightly, thereby the tension force of trim cover material 30 increases.
On the other hand, adjusting arm 66,68 makes adjusting arm 66,68 move away from each other along the rotation of loosening direction.Adjusting arm 66,68 this moves dorsad owing to make cable and damper ends 50,52 outwards move away from base portion 56, thereby cable 46 length are increased, and reduced the tension force of cable 46.Like this, the outer peripheral edges 32 of trim cover material 30 are loosened the cooperation around seat frame 16, thereby the tension force of trim cover material 30 reduces.
44 pairs of trim cover material 30 tension force adjustment of stretching device make trim cover material 30 can be installed to seat assembly at an easy rate and remove from it.In addition, the tension adjustment of trim cover material makes seat assembly 10 can adapt to different occupants' body-contoured.
Describe the present invention by diagramatic way.Should be appreciated that the term that uses is descriptive and nonrestrictive.According to above-mentioned teaching multiple improvement and variant can be arranged.Therefore, the present invention can implement within the scope of the appended claims and be not only such as specific descriptions ground implement.
