Abstract
ABSTRACT A seat weight measuring apparatus having enough strength against load in a direction in which a rear side of the vehicle seat is lifted. The seat weight measuring apparatus includes a base frame with a mounting portion at the rear end side of the base frame. The mounting portion includes two stopper bolts as protective mechanisms for transmitting excessive load from a rear rail bracket to the base frame. One stopper bolt is a front (first) stopper bolt, and the other is a rear (second) stopper bolt. Therefore, the mounting portion has higher capability to withstand load than a mounting portion at the front end side of the base frame.
Claims12
A seat weight measuring apparatus for measuring a seat weight including the weight of a passenger sitting on a vehicle seat comprising:
- a base frame fixed to a vehicle floor;
- front and rear rail brackets which are located near front and rear ends of the base frame, respectively, and are connected to a seat rail which is slidable in the frontward and rearward directions of the vehicle;
- a sensor portion which is mounted on the base frame for detecting the load applied from the rail brackets to the base frame;
- whereinthe sensor portion includes a distortion sensor fixed at the middle in the longitudinal direction of the base frame and arms which are disposed at a front portion and a rear portion of the base frame, respectively, to extend in the longitudinal direction, each arm having at its one end a press portion for transmitting force to the distortion sensor and at its other end a connecting portion relative to the rail bracket;
- wherein protective mechanisms are disposed around the front and rear rail brackets so that when the load applied on the rail brackets and the base frame exceeds a predetermined value, the protective mechanisms transmit the excessive load between the rail brackets and the base frame or the vehicle floor directly and not through the arms;
- and
- whereinthe protective mechanism at the rear side is provided with a reinforcing member for providing reinforcement against the load in a direction in which the rail brackets are lifted upward.
A seat weight measuring apparatus for measuring a seat weight including the weight of a passenger sitting on a vehicle seat comprising:
- a base frame fixed to a lower side of a seat frame below the vehicle seat;
- front and rear rail brackets which are located near front and rear ends of the base frame, respectively, and are connected to a seat rail which is slidable in the frontward and rearward directions of the vehicle;
- a sensor portion which is mounted on the base frame for detecting the load applied from the rail brackets to the base frame;
- wherein the sensor portion includes a distortion sensor fixed at the middle in the longitudinal direction of the base frame and arms which are disposed at a front portion and a rear portion of the base frame, respectively, to extend in the longitudinal direction, each arm having at its one end a press portion for transmitting force to the distortion sensor and at its other end a connecting portion relative to each rail bracket;
- wherein protective mechanisms are disposed around the front and rear rail brackets so that when the load applied on the base frame and the rail brackets exceeds a predetermined value, the protective mechanisms transmit the excessive load between the base frame and the rail brackets directly and not through the arms;
- and
- wherein the protective mechanism at the rear side is provided with a reinforcing member for providing reinforcement against the load in a direction in which the base frame is lifted upward.
A seat weight measuring apparatus for measuring a seat weight including the weight of a passenger sitting on a vehicle seat, comprising:
- a base frame extending in the frontward and rearward directions of the vehicle;
- rail brackets which are located near front and rear ends of the base frame, respectively, to interpose between the base frame and a seat rail which is slidable in the frontward and rearward directions of the vehicle;
- a sensor portion which is mounted on the base frame;
- whereinthe sensor portion includes a distortion sensor fixed at the middle in the longitudinal direction of the base frame and arms which are disposed at a front portion and a rear portion of the base frame, respectively, to extend in the longitudinal direction, each arm having at its one end a press portion for transmitting force to the distortion sensor and at its other end with a connecting portion relative to the each rail bracket;
- and
- wherein tip ends of the press portions of the arms are covered with resin caps.
