A first pressure-sensitive switch group of a seating sensor includes first pressure-sensitive switches (SWto SW) and second pressure-sensitive switches (SWto SW) located on one side of a seat in a left-right direction from the first pressure-sensitive switches, and includes a first pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), and the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW) located between the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), a second pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), and a third pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), in which seating is detected when both the first pressure-sensitive switch and the second pressure-sensitive switch in at least one of the first to third pressure-sensitive switch pairs are turned on.

Seating sensor and seat device

The present invention relates to a seating sensor. the base tableincludes a first partprovided with the sensor portionand a second partprovided with the connector portion, and the second partis arranged within a minimum rectangular area Scontaining the first part

Seating sensor with compactly arranged elements

This load cell attachment structure includes a male screw which is formed on a load sensing part of the load cell, a nut which attaches the load cell to the attachment plate by engaging with the male screw, and a wave washer which is disposed between the attachment plate and the nut.

Load cell attachment structure

A passenger's weight measurement device for a vehicle seat, capable of suppressing generation of an initial load, has a pair of slide rails extending in parallel and fixed to the vehicle floor, and a pair of side frames that support the seat and are disposed above the pair of slide rails. Load cells are disposed between the pair of the slide rails and the pair of the side frames. A set of first connection frames for connecting both ends of the pair of side frames extend in parallel to be perpendicular to the pair of side frames. Second and third connecting frames connect middle parts of the pair of slide rails so as to be perpendicular to the slide rails. The pair of the slide rails and the second and a third connecting frames constitute an H-shaped frame. The load cells include an elastic member having a varied-diameter portion.

A thin, film-form seating switch able to detect whether an occupant sits on the seat or not, wherein, with a spacer () in-between, a film-form substrate () is disposed on one surface of the spacer and a film-form member () on the other surface, a first conductor () equipped with a first terminal () and a first electrode (A) conductive with this and a second conductor () equipped with a second terminal () and a second electrode (A) conductive with this are fixed to one surface of the film-form substrate, and a third conductor (A) for letting the first electrode conduct with the second electrode when an occupant is seated is fixed to the film-form member (). The above arrangement solves a conventional problem that it is troublesome to connect the connection terminals of wires or the like provided on a wiring harness or the like to respective terminals that are separately provided on a film-form substrate and a film-form member.

A vehicle occupant sensing system includes a plurality of image pickup devices arranged to capture a three-dimensional image in a region including at least a cover part of the front airbag system and an upper part of the front passenger seat, and a signal processing unit for processing image signals taken by the image pickup devices to determine a three-dimensional position of the captured image. The signal processing unit is configured to determine a three-dimensional position of a part of the captured image pertaining to the cover part and includes a storage section which stores in advance a reference three-dimensional position corresponding to an external configuration of the cover part, and a comparing section which compares the three-dimensional position of the image part pertaining to the cover part with the reference three-dimensional position to determine if there is an object placed on the cover part.

Vehicle occupant sensing system

There is disclosed a passenger's weight measurement device for a vehicle seat, capable of suppressing generation of an initial load. The passenger's weight measurement device includes an upper rail disposed to be movable back and forth on a lower rail fixed to a vehicle floor; a load sensor fixed on the upper rail; and a frame disposed on the load sensor and below a vehicle seat, wherein a rod extends from the load sensor to penetrate the frame and to be inserted into an insertion hole formed in a center of a leaf spring, the leaf spring is curved into an angle shape to separate the center of the leaf spring from the frame, a nut is engaged with the rod on the leaf spring, and both hems of the leaf spring abut on the frame in a state that the leaf spring is fastened by the nut.

A seat-weight sensor includes a load cell having a load sensor arranged therein and a support for holding a support shaft of the load cell. The support includes a convex portion to hold the support shaft and a pair of flange portions arranged at both sides of the convex portion and fixed to a vehicle floor side. The support has a pair of slots arranged at a perimeter of the convex portion and for reducing a physical effect that the pair of flanges provides to the convex portion.
