The specific embodiment
Referring now to Fig. 1 to Fig. 4, describing has a seat back structure 1, and it is one of the parts that constitute the back of seat of a vehicle seat according to an embodiment of the invention.Seat back structure 1 comprises a top 10, separates a left and right sides sidepiece 11,12 and a bottom 13 that is provided with mutually.Top 10 connects the upper part of left and right sides sidepiece 11,12.Bottom 13 connects the lower part of left and right sides sidepiece 11,12.Whole seat back structure is by making such as the light alloy of magnesium alloy, aluminum alloy or similar material.Light and magnesium alloy reusable edible of the preferred working weight of whole seat back structure is made by the method for die casting or injection molding.
A part that comprises the seat back structure 1 of top 10 and left and right sides sidepiece 11,12 forms the profile that is roughly the shape of falling U.Top 10 comprises a lordosis top board 10a, and it comprises two circular arc shoulders, a back plate 10b, from the trailing edge of top board 10a to seat back structure 1 inboard vertical extent and along the lower edge of back plate 10b with by the cambered outwards first ruffle part 10c of this lower edge.Top board 10a, the back plate 10b and the first ruffle part 10c provide the anti-crawl agentdefiection degree for top 10.Left side 11 comprise one from top a shoulder of 10 extends downwards and the first side plate 11a of lordosis continuously, with one perpendicular to the first side plate 11a, along the first side plate 11a rear side, the first plate portion 11b that 10 back plate 10b extends downwards continuously from top, and one along originating from the first plate portion 11b the first ruffle part 10c extends downwards continuously and the second ruffle part 11c of lordosis.Equally, right side 12 comprise one from top a shoulder of 10 extends downwards and the first side plate 12a of lordosis continuously, with one perpendicular to the second side plate 12a, along the second side plate 12a rear side, the second plate portion 12b that 10 back plate 10b extends downwards continuously from top, and one along originating from the second plate portion 12b the first ruffle part 10c extends downwards continuously and the 3rd ruffle part 12c of lordosis.The first and second side plate 11a, 12a, the first and second plate portion 11b, 12b and the second and the 3rd ruffle part 11c, 12c sidepiece 11,12 to the left and right provides the anti-crawl agentdefiection degree.
For detouchable one headrest (not shown) can be installed on seat back structure 1, seat back structure 1 has the cylindrical stent 14a of a pair of separation, and 14b admits and the support headrest is placed wherein. Cylindrical stent 14a, 14b are installed on the seat back structure 1, so that extend downwards from top board 10a along back plate 10b.In addition, as shown in Figure 1 and Figure 4, at the first and second side plate 11a, the lower part of 12a provides lateral bracket 15a, 15b respectively.With lateral bracket 15a, 15b safety is fixed in seat chair cushion framework (not shown) with screw.
Reclining apparatus 2 comprises and is installed on the first and second side plate 11a, the cam gear 2a of 12a outside face lower part, 2b, one 13 extends and connects described cam gear 2a along described bottom, the axle drive shaft 2c of 2b, pass cam gear 2a with being installed on, the control lever (not shown) on axle drive shaft 2c one end of one of 2b.Adjusted with respect to the back of seat inclination angle of Chain cushion and make back of seat carry out the pivot rotation by the manipulation operation axle with respect to Chain cushion.
Except that each assembly of above-mentioned seat back structure, the axial region that centers on axle drive shaft 2c also is equipped with one by light alloy, as aluminium or the made pipe fitting 3 of similar material.The effect of described pipe fitting 3 is to strengthen seat back structure 1 bottom of the tabular bottom 13 that includes a width.In addition, when the external force just like collision put on the seat back structure, pipe fitting 3 can be shared this external force with tabular bottom 13.Therefore, can provide external force anti-crawl agentdefiection degree or obstruction degree to the seat back structure bottom.
In described example, used the pipe fitting of a length as an example pipe fitting 3 as Y, this is shorter in length than the length X (X＞Y sees Fig. 1) of axle drive shaft 2c.Thereby, being applied in the external force institute bending of seat back structure even comprise the pipe fitting 3 of axle drive shaft 2c, the pipe fitting 3 that is shorter in length than the length of axle drive shaft 2c can not insert yet.Therefore the impact energy of external force generation will be absorbed effectively owing to pipe fitting 3 comprises the bending of axle drive shaft 2c.
Refer again to Fig. 1 and Fig. 5, can be pipe fitting 3 the garter spring 4a that is installed on pipe fitting 3 both ends, 4b are provided.Thereby pipe fitting 3 is vacant around described axle drive shaft 2c.Garter spring 4a, 4b are made as silicone resin or similar material by smooth resin material.Therefore, when described reclining apparatus is operated that axle drives and when making axle drive shaft 2c rotation, the noise that friction caused that does not hinder the rotation of axle drive shaft 2c and can avoid producing by between axle drive shaft and the pipe fitting.
In the dependence vehicle seat seat that provides by the light alloy seat back structure of organizing structure as mentioned above, pipe fitting 3 is installed around the axial region of axle drive shaft 2c.Therefore it is very easy and can not influence reclining apparatus 2 is mounted on the seat back structure that pipe fitting 3 is installed.
Except that pipe fitting 3, also have a banded flexible metal sheet 5 as steel plate or similar plate along the rear surface longitudinal direction of seat back structure bottom 13, and be fixed on the bottom 13, as shown in Figure 6.Therefore the lower part of described seat back structure has further been strengthened by metal sheet 5.Also have, overflexing when putting on the seat back structure as external force even be forced to bottom 13 as collision, also can prevent that effectively this type of of bottom 13 is overflexing by flexible metal sheet 5.
Referring now to Fig. 7, flexible metal sheet 5 can be by at least two horizontal-extending hole 5a that separate mutually, and 5b forms.Screw 6a, 7a are by horizontal-extending hole 5a, and the core roughly of 5b passes bottom 13, use described screw 6a, 6b and nut 7a, and 7b is anchored on flexible board 5 on the bottom 13.
If strip metal plate 5 is applied to be fixed on the bottom 13 on the bottom 13 and with screw and nut, even bottom 13 is fractureed by power such as for example collisions, comprise screw 6a, 6b and nut 7a, the securing device quilt of 7b is along horizontal-extending hole 5a, and 5b moves, and strip metal plate 5 is simultaneously by bending, admit and support the break-off portion of bottom 13, as shown in Figure 8.Thus, can prevent the excessive evagination of break-off portion of bottom 13 effectively by band-like plate 5.
When on 13 rear surfaces, bottom, using in the embodiment shown and fixedly band-like plate 5 time, band-like plate can be used and be fixed on 13 front surfaces of bottom.
Knowing those skilled in the art should approve, any change of making at the foregoing description or change the inventive concept that does not all break away from broadness of the present invention.Therefore it should be understood that the present invention is not limited only to specific embodiment described here, any modification that the present invention is carried out or change all should be encompassed in the middle of the protection domain and spirit of appended claims of the present invention.
