no. 1 Embodiment approach

[0102] Figure 7 It is a figure which shows the schematic structure of the seating detection switch 1 which concerns on 1st Embodiment of this invention.

[0103] Figure 8 is a representation of Figure 7 The VIII-VIII section diagram, Figure 9 is a representation of Figure 7 Diagram of the IX-IX section. 8 and 9 are enlarged drawings of the thickness direction of the seating detection switch 1 (the up-down direction in FIG. 8 and the left-right direction in FIG. 9 ).

[0104] The seat occupancy detection switch 1 is, for example, a thin film-shaped occupancy detection switch that is arranged on the back side of the surface of an automobile seat and can detect whether or not an occupant is seated on the seat.

[0105] The seating detection switch 1 has a film-shaped base material 3 made of an insulator. On one side of the film-form base material 3, a spacer 5 made of an insulator is interposed, and a film-form member 7 made of an insulator is provided slightly apart from ...

no. 2 Embodiment approach

[0132] Figure 13 It is a figure which shows the schematic structure of the seating detection switch 41 concerning 2nd Embodiment of this invention.

[0133] The seating detection switch 41 differs from the seating detection switch 1 in the shapes of the film base 43 , the spacer 45 , and the film member 47 and the provision of nine switch parts 49A to 49I. Other points are basically the same configuration as the seating detection switch 1 .

[0134] That is, the film-like substrate 43, the spacer 45, and the film-like member 47 of the seating detection switch 41 are divided into three branches on the side opposite to the side where the terminal portions 9, 15 are provided, and three switches are provided on each branch. department. The switch units 49A to 49I constitute an OR circuit.

[0135] On the side of the film-form base material 43 where the terminal portions 9 and 15 are provided, the site (portion) 51 from which the spacer 45 and the film-form member 47 are remove...

no. 3 Embodiment approach

[0172] Figure 16 It is a figure which shows the schematic structure of the seating detection switch 61 which concerns on 3rd Embodiment of this invention.

[0173] The difference between the seating detection switch 61 and the seating detection switch 41 according to the second embodiment is that the portions 63A, 63B, and 63C where the pads and film-like members are removed are further separated from the terminal portions 9, 15, and the branches are three. The intermediate portions of the individual film-like substrates 63 are formed to be long. Other points are basically the same configuration as the seating detection switch 41 .

[0174] Next, a state in which the seating detection switch 61 is installed on the seat 73 of the automobile will be described.

[0175] Figure 17 It is a figure which shows the state which installed the seating detection switch 61 in the seat 73 of an automobile.

[0176] The seat 73 is composed of a seat portion 75 and a back portion 77. Th...

Abstract

A thin film-shaped seating detection switch capable of detecting whether an occupant is seated on a seat, wherein a film-shaped gasket (5) is sandwiched and a film-shaped substrate (3) is disposed on one side of the gasket, A film-shaped member (7) is disposed on the other surface, and a first conductor (13) having a first terminal portion (9) and a first electrode portion (11A) electrically connected to it is adhered to one surface of the film-form substrate. ) and a second conductor (19) having a second terminal portion (15) and a second electrode portion (17A) in electrical communication with the second conductor (19) are adhered to the film member (7) so that the second A third conductor (21A) conducting conduction between the first electrode portion and the second electrode portion. According to this configuration, the terminal portion is provided separately for the film-form base material and the film-form member, and the problem of difficulty in connecting the terminal portion to the connecting terminals of electric wires and the like provided in the electric wire harness or the like is solved.

Description

technical field [0001] The present invention relates to a seat occupancy detection switch for detecting whether a person is seated on a seat, and particularly relates to a film-shaped switch having a three-fold structure by sequentially laminating a film-shaped base material, a film-shaped spacer, and a film-shaped member. The seat detection switch. Background technique [0002] Conventionally, a thin film-shaped seat occupancy detection switch capable of detecting a person sitting on a seat is known, for example, as described in JP-A-9-315199 and JP-A-2909961. The seating detection switch has: an electrode part adhered to one film surface of a pair of films and electrically connected by a line; and an electrode part adhered to the opposite surface of the other film and one film and electrically connected by a line ; and spacers that make these electrode parts often separate and opposite to each other and disposed between the two films. In this way, when a person sits on t...
