Shoulder belt fixed parts 22 is provided with for the passenger who is sitting in seat 10 central authorities, and it is fixed on the upper frame 42.At this moment, one of them of inboard central frame 46 is configured in the below of shoulder belt fixed parts 22.By the configuration structure of so inboard central frame 46, be applied to load on the shoulder belt fixed parts 22 and be applied to again on the inboard central frame 46 of the below that is positioned at shoulder belt fixed parts 22 after by upper frame 42.Be penetrated with safety strap 23 in the shoulder belt fixed parts 22.Safety strap 23 passes shoulder belt fixed parts 22, crosses the upside of upper frame 42 then.
As shown in Figure 3, the cardinal extremity of safety strap 23 is wound on the constriction device 21.The back side 41a of top 23a from constriction device 21 beginnings along backrest frame 41 extends towards shoulder belt fixed parts 22, and, pass the upside of crossing upper frame 42 behind the shoulder belt fixed parts 22 and forwards extend, as shown in Figure 1, be fixed on the base plate side fixed part 23b of base plate 11.Base plate side fixed part 23b is positioned at the place ahead of constriction device 21, and is arranged on the below of shoulder belt fixed parts 22.
And seat 10 comprises that load bears portion 70.Load is born portion 70 and is comprised load support parts 71 and baffle plate 72.Load support parts 71 are fixed after being welded in lower frame 43, and it extends to base plate 11 from lower frame 43.Load support parts 71 are formed by tubing.And tubing is that for example metal is made.And it is welding that the fixing means of load support parts 71 is not limited to.
As shown in Figure 2, load support parts 71 are fixed near the lower end of inboard central frame 46 of the below that is positioned at shoulder belt fixed parts 22.As shown in Figure 3, load support parts 71 form the second rearward crooked curve 71a.Relative as near the position base plate side end 71b of the lower end of load support parts 71 and the base plate side fixed part 23b.
Baffle plate 72 is installed on the base plate 11, makes its base plate side end 71b with load support parts 71 relative.Baffle plate 72 is used to prevent the base plate side end 71b and base plate 11 direct contacts of load support parts 71, strengthens base plate 11 simultaneously.And, because baffle plate 72 is arranged near the position of the base plate side fixed part 23b of safety strap 23, so, near the rigidity of the base plate 11 the base plate side fixed part 23b improved.
The base plate side end 71b of load support parts 71 does not contact with baffle plate 72, forms space A between base plate side end 71b and the baffle plate 72.Space A is arranged to that load support parts 71 do not contact with baffle plate 72 when backrest frame 41 falls down.And the interval of space A for example is about 10mm.
When automobile normal running etc., 41 pairs of load that apply by safety strap 23 and shoulder belt fixed parts 22 of backrest frame have enough intensity.
Secondly, bearing portion 70 about load is illustrated in the automobile action that backrest frame 41 is applied under the load condition greatly that bumps when waiting.When automobile bumps etc., will apply bigger load apace to safety strap, at this moment, because forbid from constriction device 21, pulling out safety strap 23, so this tensile load is after-applied to backrest frame 41 by shoulder belt fixed parts 22.
As shown in Figure 4, upper frame 42 is owing to take place to the side-prominent bending of base plate 11 by the composition towards base plate 11 sides in the load that applies after the shoulder belt fixed parts 22.In Fig. 4, the deflection of backrest frame 41 is shown more large.
Because the effect towards the composition of base plate 11 sides in this load, the inboard central frame 46 that is positioned at shoulder belt fixed parts 22 belows is towards base plate 11 side shiftings.Because the composition in base plate 11 sides in the load that is applied by inboard central frame 46, lower frame 43 take place to the side-prominent bending of base plate 11.Therefore, load support parts 71 according to the bending of lower frame 43 towards base plate 11 side shiftings.
At this moment since on safety strap 23 applied load, so the load that base plate 11 is lifted also acts near the base plate side fixed part 23b the base plate 11.
Load on being applied to shoulder belt fixed parts 22 is during greater than specified value, load support parts 71 to base plate 11 side shiftings until contacting with baffle plate 72.Load support parts 71 are with after baffle plate 72 contacts, and are applied to the inboard central frame 46 that load on the backrest frame 41 is passed through shoulder belt fixed parts 22 belows again by shoulder belt fixed parts 22, are supported by load support parts 71 at last.So, in addition, can also prevent that backrest frame 41 from deforming.
And when the load on being applied to shoulder belt fixed parts 22 was big, load support parts 71 were by coming the absorbing load amount since the second curve 71a bending.And, when being applied to load on the backrest frame 41 and making upper frame 42 and lower frame 43 distortion, also can be out of shape and absorb by the first curve 45b of outside central frame 45.And the load that is applied on the backrest frame 41 is applied on the framework 31 of attending a banquet by joint portion 60.The load that is applied on the framework 31 of attending a banquet absorbs by deforming near the frame side joint portion 62 of attending a banquet.
When automobile normal running etc., the backrest frame 41 of seat 10 is for having enough intensity through safety strap 23 and shoulder belt fixed parts 22 after-applied load, so, when automobile normal running etc., do not deform.
And the bigger load that automobile is applied to when bumping etc. on the backrest frame 41 is heavy, by inboard central frame 46, support by the load support parts 71 that contact with baffle plate 72 then, so, can suppress the deflection of backrest frame 41.That is, 10 of seats just have enough intensity on backrest frame 41.Therefore, aspect the reinforcement that is applied to the load on the safety strap 23, do not need to be installed in the heavier reinforcement materials such as plate of backrest frame 41 sheet metal system on the whole about backrest frame 41, so, can realize lightweight.That is, seat 10 can also be realized the lightweight of seat 10 when keeping enough intensity.
And, because between the base plate side end 71b of load support parts 71 and baffle plate 72, formed space A, so backrest frame 41 can forwards fall down.And space A can play the effect of the curve that replaces upper frame 42 and lower frame 43, so, the tensile load that is applied on the safety strap 23 can be absorbed fully.And, form by backrest frame 41 and load support parts 71 usefulness metallic tubing, can make seat 10 further lightweights.
And on base plate 11, baffle plate 72 is installed on the position relative with the base plate side end 71b of load support parts 71.Therefore, can prevent the base plate side end 71b and base plate 11 direct contacts of load support parts 71, and reinforcing soleplate 11.And, by baffle plate 72 is installed, improved near the rigidity of the base plate 11 of base plate side fixed part 23b near the position base plate side fixed part 23b, so, can suppress to cause the distortion of base plate 11 by the load that desire is lifted base plate side fixed part 23b.
In addition, the position of shoulder belt fixed parts 22 is not limited to the upper side extending part of inboard central frame 46, also on the position shoulder belt fixed parts 22 is installed in its vicinity; Base plate side fixed part 23b is set below shoulder belt fixed parts 22, and constant-acting load support component 71 near the lower side extending part of the inboard central frame 46 the shoulder belt fixed parts 22 also can obtain the effect identical with the seat 10 of present embodiment.
