[the 2nd execution mode]
Figure 13 is the figure that the summary of the related seating detection switch 41 of expression the 2nd execution mode of the present invention constitutes.
Seating detection switch 41 is the shape of film like base material 43, pad 45, film like portion material 47 and is provided with 9 switch portion 49A～49I with the difference of seating detection switch 1.Other point is same formation with seating detection switch 1 substantially.
That is, the film like base material 43 of seating detection switch 41, pad 45, film like portion material 47 are divided into 3 branches at the opposition side of a side that is provided with portion of terminal 9,15, are provided with 3 switch portion on every.Switch portion 49A～49I has constituted or circuit.
In a side that is provided with portion of terminal 9,15 of film like base material 43, the position (part) 51 of having removed pad 45 and film like portion material 47 is made as long.
Secondly, the state that is provided with seating detection switch 41 on the seat 53 of automobile is described.
Figure 14 is the figure that has removed the state of seating detection switch 41 that is provided with that the epidermis in the outside that covers seat 53 represents on the seat 53 of automobile.Therefore, under the state that the automobile that is provided with seat 53 is sold, used, seating detection switch 41 is covered by epidermis, cannot see from the outside.
Seat 53 is made of seat portion 55 and back-rest 57, the Width central portion of seat portion 55, in order to allow the occupant sit comfortablely, is divided into position, front side 55A, middle part 55B, these 3 positions of rear side position 55C.
Seating detection switch 41 is along the surface of rear side position 55C and be provided with, and position 51 sides of having removed pad, film like portion material are towards seat 53 rears.The leading section at position 51 (leading section of the rear side of seat 53) is entering between seat portion 55 and the back-rest 57, and wiring harness extends out from each portion of terminal 9,15 of the leading section that is arranged on position 51.In addition, portion of terminal 9,15 and wiring harness are hidden in seat 53 behind, do not occur in Figure 14.
The occupant takes the words of seat 53, because this occupant's body weight, among switch portion 49A～49I at least 1 will conducting (becoming connection), on the 55C of rear side position, the position that occupant's body weight applies in a large number is promptly from subsiding to downside greatly than the marginal position to rear side position 55C and middle part 55B, the position a little on the front, line of demarcation of rear side position 55C and backrest 57.Seating detection switch 41 can 51 bendings (deflection) greatly at the position along with this pit.
For position 51, as mentioned above, removed pad 45 and film like portion material 47, constitute by film like base material 43 with the lead of its adhesion, the thickness attenuation.Like this, even 51 seating detection switch 41 are in thickness direction bending (deflection) greatly at the position, the stress that produces on the 51 film like base materials 43 of position also can diminish.Therefore, take the action that seat 53 gets up from seat 53 then even carry out the occupant repeatedly, make at the position 51 to carry out big bending repeatedly, position 51 is not fragile yet.
Also have, the pad 45 that the two sides has viscosity is not set on the position 51.Like this, even carry out big bending repeatedly, yet can not be transferred on the pad 45 and peel off from film like base material 43 with lead (the 1st conductor) 59A, lead (the 2nd conductor) 59B of film like base material 43 adhesion.Therefore, can do one's utmost to suppress the generation of fault of the seating detection switch that broken string caused 41 of lead 59A, 59B.
In addition, in the above description, form position 51 and strengthened position 51, but, also can constitute and strengthen position 51 by other at bending by unfertile land very.
Propose concrete example herein, this reinforcement is described.
Figure 15 is the perspective view that has amplified the XV portion of Figure 13.
As the position 51 of crooked greatly part is by removing pad 45 and film like portion material 47, covers the 1st conductor (lead) 59A and the 2nd conductor (lead) 59B and is provided with on the one side of film like base material 43 that the thin resist layer 200 of insulating properties strengthens.
Resist layer 200 is made of synthetic resin such as polyester, is arranged on by printing on the one side of film like base material 43.The degree of resist layer 200 thick 15 μ m has flexibility.
Resist layer 200 is to form on the one side of film like base material 43 after conductor 59A, the conductor 59B, in the crooked greatly part (position 51) of seating detection switch 41, forms on the one side of film like base material 43.
Film like portion material 47 is that portion's material of the insulating properties of 100 μ m degree constitutes by thickness.Pad 45 is that portion's material of the insulating properties of 150 μ m degree constitutes by for example thickness, in order to make film like base material 43 and film like portion material 47 bonded to each other, has adhesion coating on the two sides.The thickness of pad 45 is that the contact for contact that makes film like base material 43 and film like portion material 47 deviates from necessary thickness under normal conditions mutually in advance.
Herein, seating detection switch 41 so tabular portion's materials are applied bending moment, make it simultaneously become convex, another side becomes concavity and crooked words, at the position of the center line of the thickness direction of plate-like portion material, deflection is zero substantially, but, along with from center line to the one side or another side (proportional substantially), deflection will increase.In addition, the plate-like portion material shrinks in the another side side in the elongation of one side side.
In part with film like portion material 47 and pad 45, in other words, press from both sides Jie's pads 45 and part bonded to each other at film like base material 43 and film like portion material 47, seating detection switch 41 is crooked greatly, and it is big that the deflection of interlayer will become.Promptly, in this part, because film like base material 43, pad 45, film like portion material 47 is superimposed, seating detection switch 41 thickenings, big from the center line of this thickness to the distance change of the one side of film like base material 43, thereby the deflection of the conductor that is provided with on the one side of film like base material 43 (lead 59A and lead 59B) is big.
Therefore because the bending of this part, perhaps since crooked repeatedly, the lead that is provided with on the one side of film like base material 43 (lead 59A and lead 59B) damages, the possibility of broken string becomes big.
Have, make seating detection switch 41 crooked greatly in this part during low temperature, the adhesion coating that is provided with on pad 45 will solidify.Because this solidifies, the conductor that is provided with on the one side of film like base material 43 (lead 59A and lead 59B) will be transferred on adhesion coating, and conductor (lead 59A and lead 59B) just may damage, break.
But, at the crooked greatly part (position 51 of seating detection switch 41; Afterbody 51), removes pad 45 and film like portion material 47, cover each conductor (lead 59A and lead 59B) and on the one side of film like base material 43, be provided with the thin resist layer 200 of insulating properties.Like this, in crooked greatly part, the distance of the one side from the thickness direction center line to film like base material 43 has diminished, and the deflection of the conductor that is provided with on the one side of film like base material 43 (lead 59A and lead 59B) is just little.
Therefore, the deflection of the conductor that is provided with on the one side of film like base material 43 (lead 59A and lead 59B) is littler than the part that is provided with pad 45, film like portion material 47, and the broken string that is caused by breakage is difficult to produce.Also have,, have flexibility, thereby conductor (lead 59A and lead 59B) can not be transferred on the resist layer 200 during low temperature, can not produce the broken string of the conductor (lead 59A and lead 59B) that is caused by transfer printing yet because resist layer 200 does not have viscous layer.
Herein, for easy understanding, propose concrete numerical value and illustrate that but, present embodiment is not limited to following numerical value.As long as the conductor (lead 59A and lead 59B) that forms is difficult for 51 crooked broken strings of position owing to seating detection switch 41, can suitably change following numerical value on the one side of film like base material 43.
The thickness of film like base material 43 is 100 μ m, and the thickness of pad 45 is 150 μ m, and the thickness of film like portion material 47 is 100 μ m, and the thickness of resist layer 200 is 15 μ m.In addition, the thickness of ignoring the adhesion coating of the thickness of comparing conductor (lead 59A and lead 59B) as thin as a wafer with the thickness of above-mentioned each material and pad 45.
In the part that is provided with pad 45, film like portion material 47, the thickness of seating detection switch 41 is 350 μ m (100 μ m+150 μ m+100 μ m).Therefore, the thickness direction center line of this part is positioned at the position of one side (face of film like base material 43) the 175 μ m (350 μ m/2) from seating detection switch 41.Also have, the conductor (lead 59A and lead 59B) that is provided with on film like base material 43 is positioned at the position of the one side 75 μ m (175 μ m-100 μ m) from seating detection switch 41.
On the other hand, removing pad 45, film like portion material 47 and be provided with the part of resist layer 200, the thickness of seating detection switch 41 is 115 μ m (100 μ m+15 μ m).Therefore, the center line of the thickness direction of this part is positioned at the position of one side (face of film like base material 43) the 57.5 μ m (115 μ m/2) from seating detection switch 41.Also have, the conductor (lead 59A and lead 59B) that is provided with on film like base material 43 is positioned at the position of the one side 42.5 μ m (100 μ m-57.5 μ m) from seating detection switch 41.
Therefore, in the occasion that makes seating detection switch 41 bendings, removing pad 45, film like portion material 47 and be provided with the part bending of resist layer 200, and comparing in the part bending that is provided with pad 45, film like portion material 47, the deflection of lead is little.
Also have, in seating detection switch 41, resist layer 200 is to enter a little between pad 45 and the film like base material 43 and form.
In other words, compare with the boundary at the position that is removed with the position that film like portion material 47 exists with pad 45, in the position side of pad 45 and 47 existence of film like portion material, resist layer 200 a little length extends and formation (with reference to the resist layer 200A of Figure 15) between pad 45 and film like base material 43.That is, pad 45, film like portion material 47 and 200 overlapping little by little distances of resist layer.
In the seating detection switch 41, because pad 45, film like portion material 47 and resist layer 200 are overlapping, so boundary at pad 45 and film like portion material 47 position that exists and the position that is removed, the conductor (lead 59A and lead 58B) that can avoid stress to be provided with on film like base material 43 is gone up and is concentrated, and can reduce the possibility that conductor (lead 59A and lead 58B) damages, breaks.
Also have, in the seating detection switch 41, resist layer 200 is covered by the boundary belt 202 that the surface has the thin film like of flexibility.
Boundary belt 202 has adhesion coating on one side.Form conductor (lead 59A and lead 58B) on the one side of film like base material 43, form resist layer 200, be provided with after pad 45, the film like portion material 47, boundary belt 202 is sticked on the surface of resist layer 200 by adhesion coating.
Boundary belt 202 can be gone up overlapping at the position (forming the position of 202A shown in Figure 15) that pad 45 and film like portion material 47 exists, also can formation on whole of film like portion material 47 sides of resist layer 200.
Be provided with boundary belt 202 and can protect resist layer 200.Also have, owing to be provided with resist layer 200, the adhesive part of boundary belt 202 just can not be in direct contact with the conductor (lead 59A and lead 58B) that is provided with on the one side of film like base material 43.Therefore, though in seating detection switch 41 bendings occasion also can prevent peeling off of conductor (lead 59A and lead 58B).
Have, for example, the thickness of boundary belt 202 is made as 50 μ m, in the part that is provided with pad 45, film like portion material 47, the thickness of seating detection switch 41 just becomes 350 μ m (100 μ m+150 μ m+100 μ m).Therefore, the center line of the thickness direction of this part is located in the position of one side (face of film like base material) the 175 μ m (350 μ m/2) from seating detection switch 41.Also have, the conductor that is provided with on film like base material 43 is positioned at the position of the one side 75 μ m (175 μ m-100 μ m) from seating detection switch 41.
On the other hand, removing pad 45, film like portion material 47 and be provided with the part of resist layer 200, the thickness of seating detection switch 41 is 165 μ m (100 μ m+15 μ m+50 μ m).Therefore, the center line of the thickness direction of this part is located in the position of one side (face of film like base material 43) the 82.5 μ m (165 μ m/2) from seating detection switch 41.Also have, the conductor (lead 59A and lead 58B) that is provided with on film like base material 43 is positioned at the position of the one side 17.5 μ m (100 μ m-82.5 μ m) from seating detection switch 41.
Therefore; in the occasion that makes seating detection switch 41 bendings; the occasion that is provided with boundary belt 202 is come compared with the occasion that boundary belt 202 is not set, and the deflection of conductor (lead 59A and lead 58B) is reduced, and the breakage of the lead that is caused by bending just is difficult to produce.
[the 3rd execution mode]
Figure 16 is the figure that the summary of the related seating detection switch 61 of expression the 3rd execution mode of the present invention constitutes.
The difference of the seating detection switch 41 that seating detection switch 61 and the 2nd execution mode are related is, position 63A, the 63B, the 63C that have removed pad and film like portion material have more separated with portion of terminal 9,15, and branch is that the pars intermedia of 3 film like base material 63 forms long respectively.Other point is same formation with seating detection switch 41 substantially.
Secondly, the state that is provided with seating detection switch 61 on the seat 73 of automobile is described.
Figure 17 is illustrated in the figure that is provided with the state of seating detection switch 61 on the seat 73 of automobile.

Other each conductor 421A, 421B, 421C, 421D also with corresponding insulation such as electrode part 411B, 417B.Under this state, seating detection switch 401 becomes off state.
When the occupant has been provided with on the seat of seating detection switch 401 seat, because occupant's body weight, at least one side in the part of the part of film like base material 403 (being provided with the position of electrode part 411A, 417A etc.), film like portion material 407 (be provided with each conductor 421A etc. position) will deflection (because the power of arrow A R1 shown in Figure 24, arrow A R3 direction and bending.And, by means of at least 1 among conductor 421A, 421B, 421C, the 421D, at least 1 group electrode part conducting mutually among electrode part 411A and 417A, electrode part 411B and 417B, electrode part 411C and 417C, electrode part 411D and the 417D.
By means of this conducting, portion of terminal 409 and portion of terminal 415 conducting mutually, seating detection switch 401 becomes on-state, passes to for example control device (not shown) of automobile by the holding wire of wiring harness.
Be provided with the occasion of seating detection switch 401 on the seat, for example, position 428 (with reference to Figure 23) is exactly the part crooked greatly because occupant has sat.
In the seating detection switch 401,, replace pad 405 and be provided with the two-sided tape thinner than pad 405 in crooked greatly part 428, thereby at the position 428, the thickness attenuation of seating detection switch 401.
Herein, seating detection switch 41 so tabular portion's materials are applied bending moment, make it simultaneously become convex, another side becomes concavity and crooked words, at the position of the center line of the thickness direction of plate-like portion material, deflection is zero substantially, but, along with from center line to the one side or another side (proportional substantially), deflection will increase.In addition, the plate-like portion material shrinks in the another side side in the elongation of one side side.
In part with film like base material 403, film like portion material 407 and pad 405, in other words, press from both sides Jie's pads 405 and part bonded to each other at film like base material 403 and film like portion material 407, seating detection switch 401 is crooked greatly, and it is big that the deflection of interlayer will become.
Promptly, in this part, because film like base material 403, pad 405, film like portion material 407 is superimposed, seating detection switch 401 thickenings, distance from the center line of this thickness to the another side (face of the opposition side of pad 405) of film like base material 403 and the distance from the center line of this thickness to the another side (face of the opposition side of pad 405) of film like portion material 407 have all become greatly.
On the other hand, position 428 at seating detection switch 401, owing to adopted the two-sided tape 430 thinner than pad 405, seating detection switch 401 attenuation have all diminished to the distance of the another side (face of the opposition side of pad 405) of film like base material 403 and the distance of the another side from center line to film like portion material 407 (face of the opposition side of pad 405) from the center line of the thickness direction of the seating detection switch on the position 428 401.
Like this, even at the position 428, seating detection switch 401 is in thickness direction crooked (deflection) greatly, and the distortion and the stress that produce on the film like base material 403 at position 428, film like portion material 407 also can diminish.Therefore, take the action that seat gets up from seat then even carry out the occupant repeatedly, make at the position 51 to carry out big bending repeatedly, position 428 is not fragile yet.
In a word, be provided with on the seat can detect the occupant whether on the seat seat thin membranaceous seating detection switch 401, even since the occupant on this seat seat make its bending greatly, seating detection switch 401 is not fragile yet.
