A closer device includes: a threaded shaft rotating by drive force of a motor; a shaft-like member threadedly engaging with the threaded shaft to transmit decelerated rotation of the threaded shaft and permit displacement in an axial direction between a first axial position and a second axial position; and a restriction member displaced between a first position at which the shaft-like member is displaced from the side of the first axial position to the side of the second axial position by restricting rotation of the shaft-like member that accompanies the rotation of the threaded shaft and a second position at which the displacement of the shaft-like member from the side of the first axial position to the side of the second axial position is restricted by permitting the rotation of the shaft-like member that accompanies the rotation of the threaded shaft.

Closer device and vehicle door locking device

A seat occupancy determination apparatus includes first and second load detection portions arranged at one end of a seat in a width direction, a peak value detection portion detecting whether a peak value of a partial load value exists within a first predetermined time period in a case where the partial load value decreases to or below a first threshold value, and a first seat occupancy determination portion shifting a determination to a no occupant state in a case where the peak value is detected and a disengagement of a tongue plate from a buckle is detected within a predetermined time while an occupant seated state is determined. The first seat occupancy determination portion is inhibited from shifting the determination to the no occupant state in a case where the peak value is detected and the disengagement of the tongue plate is inhibited from being detected within the predetermined time.

Seat occupancy determination apparatus

An apparatus for determining a seat occupancy includes a load detecting portion provided between one of a front portion and a rear portion of a seating portion of a seat for a vehicle that includes a lifting function for changing a height position of the seating portion relative to a floor for the vehicle, the seat including a seat back at the rear portion of the seating portion of the seat, the load detecting portion detecting a seating load applied to the seating portion, and a seat occupancy determining portion comparing the seating load detected by the load detecting portion with a predetermined threshold value and determining a seat occupancy state of the seat, the seat occupancy determining portion changing the threshold value based on the height position of the seating portion.

Apparatus and method for determining seat occupancy

A load detection device for a vehicle seat mounted between a floor side mounting mechanism and a seat side mounting mechanism and measuring a load applied by an occupant seated on the vehicle seat, includes a shaft member adapted to be fixed to one of the floor side mounting mechanism and the seat side mounting mechanism, a strain generating member fixed to the shaft member and including a hole into which the shaft member is press-fitted, a strain gauge attached to the strain generating member, the shaft member of which surface hardness is specified to be lower than a surface hardness of the hole and including a scraping projecting portion scraped off by means of the hole in a case where the shaft member is press-fitted to the hole, and an inter space formed between the strain generating member and the shaft member and positioned next to the scraping projecting portion.

Vehicle seat load detection device having interspace to receive projecting portion scraped off from press-fitted shaft member

A seat apparatus for a vehicle, includes a seat-side fixing member, a slide rail, a load detecting device disposed between the seat-side fixing member and the slide rail and arranged at an end portion of the slide rail on a rear side of the vehicle, and a bracket arranged at an end portion of the slide rail on a front side of the vehicle, the bracket supporting the seat-side fixing member. The bracket includes a lower attachment portion attached to the slide rail, a supporting portion extending from the lower attachment portion toward an upper side of the vehicle, and an upper attachment portion connected to the supporting portion so as to extend from the supporting portion toward the rear side of the vehicle, thereby being cantilever-supported by the supporting portion, and attached to the seat-side fixing member at a free-end side of the upper attachment portion.

Vehicle seat apparatus having load detecting device

A load detection device for a vehicle seat mounted between a floor side mounting mechanism made of metal and a seat side mounting mechanism made of metal and measuring a load applied by an occupant seated on the vehicle seat includes a strain generating body adapted to be fixed via both end portions to a fitting surface formed at one of the floor side mounting mechanism and the seat side mounting mechanism while having a predetermined clearance from the fitting surface, a strain gauge attached to the strain generating body, a bracket made of metal and including an attachment portion that extends laterally relative to the strain generating body, and an amplifier substrate mounted on the attachment portion while being arranged in parallel to the strain generating body, both surfaces of the amplifier substrate being covered by one of or more of the bracket, the floor side mounting mechanism and the seat side mounting mechanism, the amplifier substrate amplifying a signal output from the strain gauge.
