Embodiment 2

With reference to Fig. 3 ~ Figure 15 to adaptor union 14 and the integrated configuration example of distribution maintaining part 15 are described in embodiment 2.Adaptor union 14 is identical with embodiment 1 with the key element beyond distribution maintaining part 15.In each configuration example, distribution component 12A ~ 12C is equivalent to respectively " distribution component 12 ", and adaptor union 14A, 14B are equivalent to respectively " adaptor union 14 ", and distribution maintaining part 15A ~ 15F is equivalent to respectively " distribution maintaining part 15 ".In addition, in order to simplicity of illustration and explanation, only otherwise express especially, just the identical Reference numeral of the element annotation identical with the key element that embodiment 1 uses is omitted the description.For each configuration example too.

1st configuration example is as described below.Illustrate adaptor union 14A and the integrated configuration example of distribution maintaining part 15A in Fig. 3 and Fig. 4.Distribution maintaining part 15A in Fig. 3 shown in three-view diagram has convex position 15a and holding part 15b etc.Convex position 15a gives prominence to shaping wall-like position along two opposed faces of adaptor union 14A.Holding part 15b is the mutual tabular position arranged of building bridge at two convex position 15a.The shape (comprising end shape, section shape) of holding part 15b, number, material, thickness etc. can set arbitrarily.

Exceed external force to can identify whether to have acted at distribution maintaining part 15A (specifically holding part 15b) at a glance, have if can be set as and exceed external force along with pulling distribution component 12A to be applied with, the material, thickness etc. of the rigidity of degree that are out of shape or cut off.Increase along with exceeding external force, the deflection increase of holding part 15b, the place of incision of holding part 15b increase.

Owing to there is the path passed through for distribution component 12A, so hereinafter referred to as path position 15c (with reference to Fig. 4) between a face (being upper surface in the diagram) of holding part 15b and adaptor union 14A.As long as the material, shape etc. of convex position 15a, holding part 15b are to make distribution component 12A shaping just any by the mode of path position 15c.

Distribution component 12A shown in Fig. 4 extends from the distribution of adaptor union 14A with hole 14a, if bend to prescribed direction (being left in the diagram), shaping 1st curve 16.Distribution component 12A, by path position 15c, extends from the distribution maintaining part 15A of the side contrary with the 1st curve 16.Further, if bending to the direction (be in the diagram right) contrary with the 1st curve 16, then shaping 2nd curve 13.

The clearance G 1 in a face of holding part 15b and adaptor union 14A can set arbitrarily, but is preferably set as more than the thickness (thickness) of distribution component 12A in the mode making distribution component 12A pass through.In brief, distribution maintaining part 15A (i.e. convex position 15a and holding part 15b) can be formed as distribution component 12A to remain the structure that can slide, and also can be formed as being remained the structure that cannot slide.Remaining in the structure that can slide at the former, even if occupant takes a seat repeatedly, distribution component 12A dislocation when standing up at every turn, also utilizes the 1st curve 16, the 2nd curve 13 absorbs this dislocation.Remain in the structure that cannot slide, because the curvature of the 1st curve 16 is maintained, so the dislocation of distribution component 12A is absorbed by the one side or both sides in the 2nd curve 13 and spring members 30 the latter.No matter which kind of sets, and reliably can both absorb the dislocation of distribution component 12A.

1st variation of the 1st configuration example is as described below.Figure 5 illustrates adaptor union 14A and the integrated configuration example of distribution maintaining part 15A, the i.e. variation of the 1st configuration example.1st variation and the 1st configuration example difference are, arrange fragile position 15d at holding part 15b.Fragile position 15d is to can identify whether acted on stronger external force at holding part 15b at a glance, along with the position that can be out of shape or cut off when pulling distribution component 12A to be applied with and exceed external force.

Fragile position 15d shown in Fig. 5 takes shape in face (below) side of holding part 15b.In addition, another side (upper surface) side of holding part 15b can be taken shape in, also can as shown in long and two-short dash line shaping multiple fragile position 15d.Take shape in which face, shaping number be several, be formed as which kind of shape (linearity, curve-like) and be formed as which kind of section shape, can with do not cause be out of shape, the allowance that cuts off sets arbitrarily accordingly.

2nd variation of the 1st configuration example is as described below.Show adaptor union 14A and the integrated configuration example of distribution maintaining part 15B, the i.e. variation of the 1st configuration example at Fig. 6.2nd variation and the 1st configuration example difference are, replace distribution maintaining part 15A and one-body molded be distribution maintaining part 15B.Specifically, replace the holding part 15b of tabular, shaping with multiple bridge formation position 15e.

A bridge formation position 15e is equivalent to the slenderly shaping position of holding part 15b.Mutual at bridge formation position 15e, can arrange graphic gap, also can arrange not shown narrow slit.Multiple bridge formation position 15e exceedes external force to can identify whether to have acted at a glance, the position that can be out of shape along with pulling distribution component 12A to be applied with to exceed external force or cut off.Increase along with exceeding external force, the place of incision of the number increase of the bridge formation position 15e of distortion, the deflection increase of bridge formation position 15e, bridge formation position 15e increases.

The shape (comprising end shape, section shape) of the bridge formation position 15e shown in Fig. 6, as long as whether number, material, thickness etc. can identify to have acted at bridge formation position 15e at a glance and exceed external force, just can set arbitrarily.That is, be shaped to which kind of shape, shaping number be several, be formed as which kind of shape (linearity, curve-like) and be formed as which kind of section shape, can with do not cause be out of shape, the allowance that cuts off sets arbitrarily accordingly.

2nd configuration example as with under.Illustrate adaptor union 14A and the integrated configuration example of distribution maintaining part 15C in Fig. 7 and Fig. 8.Distribution maintaining part 15C in Fig. 7 shown in three-view diagram has convex position 15a, extending area 15f etc.Extending area 15f is the tabular position arranged in the mode of stretching out respectively from two convex position 15a.At extending area 15f, clearance G 2 is set each other.The interval of clearance G 2 can set arbitrarily.The shape (comprising end shape, section shape) of extending area 15f, number, material, thickness etc. can set arbitrarily.

Exceed external force to can identify whether to have acted at distribution maintaining part 15C (specifically extending area 15f) at a glance, and can be set as having the material, thickness etc. that are applied with the rigidity exceeding the degree that external force can be out of shape or cut off along with pulling distribution component 12A.Increase along with exceeding external force, the deflection increase of extending area 15f, the place of incision of extending area 15f increase.

Owing to there is the path passed through for distribution component 12A, so hereinafter referred to as path position 15c (with reference to Fig. 4) between a face (being upper surface in the figure 7) of extending area 15f and adaptor union 14A.As long as the material, shape etc. of convex position 15a, extending area 15f are to make distribution component 12A shaping just any by the mode of path position 15c.

The distribution component 12A shown in distribution component 12A and Fig. 4 shown in Fig. 8 is same, is provided with the 1st curve 16 and the 2nd curve 13.Wherein, the path position 15c shown in Fig. 8 is formed by a face (being upper surface in fig. 8) of extending area 15f and adaptor union 14A.The clearance G 3 in a face of extending area 15f and adaptor union 14A can set arbitrarily, but is preferably set as more than the thickness (thickness) of distribution component 12A in the mode making distribution component 12A pass through.

The variation of the 2nd configuration example is as described below.Although not shown, extending area 15f also can carry out the distortion identical with the 1st configuration example.That is, also the fragile position 15d shown in Fig. 5 can be taken shape in extending area 15f or the such shaping extending area 15f of bridge formation position 15e as shown in Figure 6.

3rd configuration example is as described below.Illustrate adaptor union 14B and the integrated configuration example of distribution maintaining part 15D in Fig. 9 and Figure 10.Distribution maintaining part 15D shown in Fig. 9 be formed as from a face (in fig .9 upper surface) of adaptor union 14B outstanding tangle position 14b.Tangle position 14b to be responsible for and to tangle and keep the function of distribution component 12B.The position 14b that tangles shown in Figure 11 and Figure 12 has the head of dish type and engages (link) with this head and adaptor union 14B and have the main part etc. of elastomeric column.

Distribution component 12B shown in Fig. 9 extends from the distribution of adaptor union 14B with hole 14a, if bend to prescribed direction (being upper left side in fig .9), shaping 1st curve 16.Make to tangle position 14b tangle and keep distribution component 12B (specifically through hole 12a), and extend from the distribution maintaining part 15D of the side contrary with the 1st curve 16.Further, if bending to the direction (be in Fig. 10 right) contrary with the 1st curve 16, then shaping 2nd curve 13.

To tangling position 14b tangling and keeping being described simply distribution component 12B.Arrow D1 as shown in Figure 9 makes distribution component 12B move like that, makes to tangle position 14b by through hole 12a.Through hole 12a can, for illustrating the hole of such circle, also can be hole that is oval, slot shape.Because the head tangling position 14b is formed as wider than through hole 12a, so the main part tangling position 14b as shown in figure 11 bends and elastic deformation.After the head tangling position 14b is by through hole 12a, head stops and keeping distribution component 12B as shown in figure 12, and the main part of elastic deformation returns initial shape (state) due to restoring force.The height (length) tangling the main part of position 14b can set arbitrarily, but in order to reliably keep distribution component 12B, is preferably set to more than the thickness (thickness) of distribution component 12B.Tangle position 14b to be made up of the two panels shown in Figure 11 and Figure 12, also can be made up of a slice, the sheet number of more than three.

4th configuration example is as described below.Illustrate adaptor union 14B and the integrated configuration example of distribution maintaining part 15E in Figure 13 and Figure 14.Distribution maintaining part 15E shown in Figure 13 is formed as from the outstanding chimeric position 14c in a face (being upper surface in fig. 13) of adaptor union 14B.Chimeric position 14c is responsible for and that to it keep function chimeric with distribution component 12C (being specifically fitted position 12b).In the example shown in Figure 13, chimeric position 14c is shaped to concavity, position 12b will be fitted and be shaped to convex.Although not shown, but also chimeric position 14c can be shaped to convex, position 12b will be fitted and be shaped to concavity.

Embodiment 3

With reference to Figure 16 ~ Figure 31 to adaptor union 14 and the independent shaping configuration example of distribution maintaining part 15 are described in embodiment 3.Adaptor union 14 and the key element beyond distribution maintaining part 15 and embodiment 1,2 identical.In each configuration example, distribution component 12A, 12B are equivalent to respectively " distribution component 12 ", and adaptor union 14A, 14C are equivalent to respectively " adaptor union 14 ", and distribution maintaining part 15G ~ 15L is equivalent to respectively " distribution maintaining part 15 " and " maintenance parts ".In addition, in order to simplicity of illustration and explanation, only otherwise express especially, just the identical Reference numeral of the element annotation identical with the key element that embodiment 1,2 uses is omitted the description.For each configuration example too.

1st configuration example is as described below.Figure 16 illustrates independent for adaptor union 14A and distribution maintaining part 15G shaping configuration example.The distribution maintaining part 15G of the 1st configuration example, to accommodate and to keep the mode of adaptor union 14A and distribution component 12A to be formed as hat shape, is equivalent to " hat shape parts ".As shown in figure 17, the predetermined surface of distribution maintaining part 15G has peristome 15x.Further, the mode that distribution maintaining part 15G is shaped to cover of distribution component 12A and a part of adaptor union 14A is as illustrated in fig. 18 accommodated it and the structure kept.Although not shown, but whole mode that also can be shaped to the part and adaptor union 14A covering distribution component 12A it is accommodated and the structure kept.

To distribution maintaining part 15G tangling and keeping being described simply distribution component 12A.The distribution component 12A extended from the distribution hole 14a of adaptor union 14A is to bending and shaping 1st curve 16 in advance of prescribed direction (being upper left side in figure 16).Under the state forming the 1st curve 16, arrow D4 as shown in figure 16 makes distribution maintaining part 15G move like that, to accommodate and keep in the mode covering distribution component 12A and an adaptor union 14A part separately to it.Also distribution maintaining part 15G can be pressed into relative to distribution component 12A and adaptor union 14A.Because the distribution component 12A after keeping extends from the distribution maintaining part 15G of the side contrary with the 1st curve 16, so further to direction (among Figure 18, Figure 19 be right) bending and shaping 2nd curve 13 contrary with the 1st curve 16.

Figure 18 illustrates the outward appearance after distribution maintaining part 15G is covered, figure 19 illustrates local section.Distribution component 12A is connected device 14A between the 2nd curve 13 and the 2nd curve 13 and distribution maintaining part 15G clamps.Therefore, at inner sustain the 1st curve 16 of distribution maintaining part 15G, shaping 2nd curve 13 in the outside of distribution maintaining part 15G.

The gap of the adaptor union 14A and distribution maintaining part 15G that clamp distribution component 12A can set arbitrarily, but is preferably set as more than the thickness (thickness) of distribution component 12A in the mode making distribution component 12A pass through.In brief, distribution component 12A can be formed as remain the structure that can slide, also can be formed as being remained the structure that cannot slide.Remaining in the structure that can slide at the former, even if occupant takes a seat repeatedly, distribution component 12A dislocation when standing up at every turn, also utilizes the 1st curve 16, the 2nd curve 13 absorbs this dislocation.Remain in the structure that cannot slide, because the curvature of the 1st curve 16 is maintained, so the dislocation of distribution component 12A is absorbed by the one side or both sides of the 2nd curve 13 and spring members 30 the latter.No matter which kind of sets, and reliably can both absorb the dislocation of distribution component 12A.

The variation of the 1st configuration example is as described below.Although not shown, but for clamp and for the distribution maintaining part 15G keeping the retaining part of the distribution component 12A corresponding sidepiece of upside (in Figure 18 and the Figure 19 for), can be formed as identifying whether act at distribution maintaining part 15G the structure exceeding external force at a glance.Specifically, can be set as having along with pulling distribution component 12A when being applied with the rigid material, thickness etc. that exceed the degree that external force can be out of shape or cut off.Also can the shaping distortion identical with the 1st configuration example of embodiment 2 and the fragile position 15d shown in Fig. 5 or bridge formation position 15e as shown in Figure 6 shaping like that.So, increase along with exceeding external force, the deflection increase, the cut-out amount that put on the position of the distribution maintaining part 15G corresponding with retaining part increase.

2nd configuration example is as described below.Figure 20 illustrates independent for adaptor union 14A and distribution maintaining part 15H shaping configuration example.Distribution maintaining part 15H is equivalent to " strapping elements ", ties up and keeps adaptor union 14A and distribution component 12A.As long as strapping elements can be tied up and be kept adaptor union 14A and distribution component 12A, material, shape etc. just can set arbitrarily.Such as, corresponding cable tie, strapping, steel wire, nylon cable tie, cord etc., can be formed as wire, long plate shape.

To distribution maintaining part 15H tying up and keeping being described simply distribution component 12A.The distribution component 12A extended from the distribution hole 14a of adaptor union 14A is to bending and shaping 1st curve 16 in advance of prescribed direction (being upper left side in fig. 20).Under the shaping state of the 1st curve 16, is wound around distribution maintaining part 15H shown in Figure 20, ties up and keep distribution component 12A and adaptor union 14A.Because the distribution component 12A after keeping extends from the distribution maintaining part 15H of the side contrary with the 1st curve 16, so further to direction (be in figure 21 right) bending and shaping 2nd curve 13 contrary with the 1st curve 16.

Figure 21 illustrates the outward appearance after covering distribution maintaining part 15H.The power of tying up of distribution maintaining part 15H can set arbitrarily.Can be formed as distribution component 12A to remain can slide tie up power, also can be formed as being remained cannot slide tie up power.Remaining in the structure that can slide at the former, even if occupant takes a seat repeatedly, distribution component 12A dislocation when standing up at every turn, also utilizes the 1st curve 16, the 2nd curve 13 absorbs this dislocation.Remain in the structure that cannot slide, because the curvature of the 1st curve 16 is maintained, so the dislocation of distribution component 12A is absorbed by the one side or both sides of the 2nd curve 13 and spring members 30 the latter.No matter which kind of sets, and reliably can both absorb the dislocation of distribution component 12A.

The variation of the 2nd configuration example is as described below.Although not shown, but distribution maintaining part 15H can be formed as can identifying the structure whether acting on and exceed external force at a glance.Specifically, the material, thickness etc. of the rigidity had along with the degree pulling distribution component 12A can be out of shape when being applied with and exceeding external force or cut off can be set as.Also can the shaping distortion identical with the 2nd configuration example of embodiment 2 and the fragile position 15d shown in Fig. 5 or bridge formation position 15e as shown in Figure 6 shaping like that.So, increase along with exceeding external force, the deflection of distribution maintaining part 15H increases, cuts off.

3rd configuration example is as described below.Figure 22 illustrates independent for adaptor union 14A and distribution maintaining part 15I shaping configuration example.Distribution maintaining part 15I have clamp distribution component 12A and carry out tangling relative to adaptor union 14A and keep tangle position 15g.As long as tangle position 15g to move as arrow D5 and hooking be held in adaptor union 14A, material, shape etc. just can set arbitrarily.A part is shaped to hook shape in the mode of a part of hooking adaptor union 14A (by tangling position) by the position 15g that tangles such as shown in Figure 22.Though take shape in leading section in fig. 22, the position (pars intermedia etc.) beyond leading section also can be taken shape in.Adaptor union 14A is tangled position and can be set arbitrarily, such as, can be bight, also can for being arranged at protuberance (projection), the recess (depression) of adaptor union 14A.Although not shown, but also can for can hooking be held in the shape (such as L-shaped shape, J-shaped shape, T-shaped shape etc.) at the arbitrary position of adaptor union 14A.

To distribution maintaining part 15I tangling and keeping being described simply distribution component 12A.The distribution component 12A extended from the distribution hole 14a of adaptor union 14A is to bending and shaping 1st curve 16 in advance of prescribed direction (being upper left side in fig. 22).Under the state forming the 1st curve 16, make distribution maintaining part 15I movement as arrow D5 as illustrated in fig. 22.Then, clamp distribution component 12A as illustrated in fig. 23, tangled and be held in adaptor union 14A.Because the distribution component 12A after keeping extends from the distribution maintaining part 15I of the side contrary with the 1st curve 16, so further to direction (be in fig 23 right) bending and shaping 2nd curve 13 contrary with the 1st curve 16.

Figure 23 illustrates the state after tangling distribution maintaining part 15I.The power that tangles of distribution maintaining part 15I can set arbitrarily.Can be formed as distribution component 12A to remain can slide tangle power, also can be formed as being remained cannot slide tangle power.Remaining in the structure that can slide at the former, even if occupant takes a seat repeatedly, distribution component 12A dislocation when standing up at every turn, also utilizes the 1st curve 16, the 2nd curve 13 absorbs this dislocation.Remain in the structure that cannot slide, because the curvature of the 1st curve 16 is maintained, so the dislocation of distribution component 12A is absorbed by the one side or both sides of the 2nd curve 13 and spring members 30 the latter.No matter which kind of sets, and reliably can both absorb the dislocation of distribution component 12A.

The variation of the 3rd configuration example is as described below.Although not shown, but the tangling position 15g and can be formed as can identifying the structure whether acting on and exceed external force at a glance of distribution maintaining part 15I.That is, can be set as that there is the material, thickness etc. along with pulling distribution component 12A to remove the rigidity of the degree tangled when being applied with and exceeding external force.

4th configuration example is as described below.Figure 24 illustrates independent for adaptor union 14A and distribution maintaining part 15J shaping configuration example.Distribution maintaining part 15J is equivalent to " hat shape parts ", there is part or all the cap position 15i that covers distribution component 12A and carry out tangling and keep relative to adaptor union 14A tangle position 15h etc.Cap position 15i is formed as the shape identical with the distribution maintaining part 15G shown in Figure 16, has the peristome 15x shown in Figure 17.As long as tangle position 15h to move as arrow D6 and hooking be held in adaptor union 14A, material, shape etc. just can set arbitrarily.Also can carry out tangling the identical distortion of position 15g with above-mentioned.

To distribution maintaining part 15J tangling and keeping being described simply distribution component 12A.The distribution component 12A extended from the distribution hole 14a of adaptor union 14A is to bending and shaping 1st curve 16 in advance of prescribed direction (being upper left side in fig. 24).Under the state forming the 1st curve 16, make distribution maintaining part 15J movement as arrow D6.Then, as illustrated in fig. 25 distribution component 12A is contained in cap position 15i, and position 15h will be tangled tangles and be held in adaptor union 14A.Because the distribution component 12A after keeping extends from the distribution maintaining part 15J of the side contrary with the 1st curve 16, so further to direction (be in fig. 25 right) bending and shaping 2nd curve 13 contrary with the 1st curve 16.

State after tangling distribution maintaining part 15J has been shown in Figure 25 and Figure 26.The position 15g that tangles shown in 15h and the Figure 23 of position that tangles shown in Figure 25 tangles equally in adaptor union 14A and keeps distribution component 12A.The distribution maintaining part 15G shown in 15i and the Figure 19 of cap position shown in Figure 26, except the curvature of the 1st curve 16 is different, accommodates it in the mode covering distribution component 12A and an adaptor union 14A part separately equally and keeps.Also distribution maintaining part 15G can be pressed into relative to distribution component 12A and adaptor union 14A.

The power that tangles of distribution maintaining part 15J can set arbitrarily.Can be formed as distribution component 12A to remain can slide tangle power, also can be formed as being remained cannot slide tangle power.Remaining in the structure that can slide at the former, even if occupant takes a seat repeatedly, distribution component 12A dislocation when standing up at every turn, also utilizes the 1st curve 16, the 2nd curve 13 absorbs this dislocation.Remain in the structure that cannot slide, owing to maintaining the curvature of the 1st curve 16, so the dislocation of distribution component 12A is absorbed by the one side or both sides of the 2nd curve 13 and spring members 30 the latter.No matter which kind of sets, and reliably can both absorb the dislocation of distribution component 12A.

The variation of the 4th configuration example is as described below.Although not shown, but the tangling position 15h and also can be set as having material, thickness etc. along with pulling distribution component 12A to remove the rigidity of the degree tangled when being applied with and exceeding external force of distribution maintaining part 15J.In addition, cap position 15i also can carry out the distortion identical with the distribution maintaining part 15G shown in the 1st configuration example.Whether no matter which kind of sets, can both identify to have acted on to exceed external force at a glance.

Describe the present invention according to embodiment 1 ~ 3 above, but the present invention does not limit this form.In other words, without departing from the spirit and scope of the invention, can also implement with various form.Such as, each variation shown below can also be realized.

Above-mentioned embodiment 1 represents basic configuration example, and embodiment 2 represents adaptor union 14 and the integrated configuration example of distribution maintaining part 15, and embodiment 3 represents independent to adaptor union 14 and distribution maintaining part 15 shaping configuration example.Although not shown, but also can the plural structure in the above-mentioned configuration example of combination in any apply.Such as, the 1st configuration example and other configuration examples (the 2nd configuration example ~ the 5th configuration example) that also can combine embodiment 2 are applied.Equally, the 2nd configuration example and other configuration examples (the 1st configuration example and the 3rd configuration example ~ the 6th configuration example) that also can combine embodiment 3 are applied.In addition, each configuration example of each configuration example and embodiment 3 that also can combine embodiment 2 is applied.If apply the combination of this configuration example, then can obtain the action effect of each applied configuration example.

The above-mentioned seat 20 shown in embodiment 1 ~ 3 is formed as having the structure (with reference to Fig. 1) of the cushion rubber 21 possessing more than one hanging groove 21a and more than one through hole 21b.Replace this form, can be formed as having the structure of the cushion rubber 21 not forming hanging groove 21a, also can be formed as the structure with the cushion rubber 21 forming through hole 21b with hanging groove 21a independently.No matter which kind of seat 20, all at distribution component 12 by identical in through hole 21b, therefore, it is possible to obtain the action effect identical with embodiment 1 ~ 3.

The above-mentioned passenger detection device 10 shown in embodiment 1 ~ 3 is formed as being the structure (with reference to Fig. 1) of linearity along the surface configuration of cushion rubber 21 by sensor element 11, distribution component 12.Replace this form (or on its basis), also can be formed as the structure at the position be configured at beyond the surface of cushion rubber 21 or be configured to the structure of non-linear shape (such as curve-like, forked etc.).No matter carry out which kind of configuration, all carry out occupant detection in identical, therefore, it is possible to obtain the action effect identical with embodiment 1 ~ 3.

In above-mentioned embodiment 1 ~ 3, can spring members 30 (with reference to Fig. 2) as the fixed part application for fixed connector 14.Replace this form, also can using the miscellaneous part except spring members 30 as fixed part fixed connector 14.Miscellaneous part is associated frame members 24, vehicle body etc. such as.Owing to only adaptor union 14 to be fixed on the difference of which parts, so the action effect identical with embodiment 1 ~ 3 can be obtained.

In above-mentioned embodiment 1 ~ 3, be formed as arranging distribution maintaining part 15 between cushion rubber 21 and adaptor union 14, the formation (with reference to Fig. 2) that distribution component 12 configures along the back side of seat 20.Replace this form, such as shown in figure 33, also can be formed as configuring adaptor union 14 between cushion rubber 21 and distribution maintaining part 15, distribution component 12 is configured to the structure linearly extended from through hole 21b.That is, make adaptor union 14 contrary with the configuration of distribution maintaining part 15.Because distribution component 12 linearly extends from through hole 21b, even if so occupant carries out taking a seat, distribution component 12 misplaces (movement), also by this dislocation of resilient absorbent of spring members 30 when standing up at every turn.Therefore, distribution component 12 is suppressed to contact with miscellaneous part further.
