Seat-load measuring apparatus
View Patent ↗A seat load measuring apparatus that includes a seat rail between a seat-load measuring apparatus and a vehicle floor. The apparatus includes a base frame and a base bracket that provide a load support mechanism to support a load heavier than a predetermined load imposed on the vehicle seat.
1. A seat-load measuring apparatus comprising:
a seat rail fixed to a vehicle body to guide a vehicle seat movably in a front-rear direction of a vehicle,
a base frame fixed to one of the vehicle seat and the seat rail to support a load imposed on the vehicle seat;
a base bracket fixed to the seat rail;
an arm supported by the base frame to receive the load imposed on the vehicle seat;
a load sensor supported by the arm to detect the load imposed on the vehicle seat; and
wherein at least one of the base frame and the base bracket include a load support mechanism to support a load heavier than a predetermined load imposed on the vehicle seat.
2. The apparatus of claim 1 , wherein the base bracket is connected to the base frame by a rivet.
3. The apparatus of claim 1 , wherein the base bracket overlies the base frame.
4. The apparatus of claim 1 , wherein the base bracket is positioned between the base frame and the seat rail.
5. The apparatus of claim 1 , wherein the base bracket is positioned to overlie a rear end of the base frame.
6. The apparatus of claim 1 , wherein both the base bracket and the base frame have a u-shape in transverse cross-section.
7. The apparatus of claim 1 , further comprising a bolt extending transversely through the base frame and the base bracket.
8. The apparatus of claim 7 , wherein the base bracket includes holes for receiving the bolt.
9. The apparatus of claim 8 , wherein the base frame includes slots for receiving the bolt.
10. The apparatus of claim 9 , wherein portions of the base frame adjacent to the slot and portions of the base bracket adjacent to the holes are configured to support a heavy load applied to the seat during a vehicle collision.
