Abstract: A vehicular crash sensing system includes a bumper cap for contacting a bumper. A chamber fits into a side rail attached to the bumper, the chamber being sealed by the bumper cap. A stop element limits movement of the chamber into the side rail. A pressure sensor detects an increased chamber air pressure during crushing of the chamber resulting from movement of the bumper with respect to the stop element.

Abstract: A vehicular crash sensing system is provided wherein a bumper cap contacts a bumper. A chamber is at least partially fit into a side rail attached to the bumper, wherein the chamber is sealed by the bumper cap. The bumper cap and chamber together enclose a space containing a volume of air. A stop element limits movement of the chamber into the side rail. A pressure sensor detects an increased chamber air pressure during crushing of the chamber resulting from movement of the bumper with respect to the stop element.

Abstract: A vehicle tailgate movement assist mechanism including a tailgate configured to rotate between opened and closed positions, and a tailgate lever arm fixedly connected to a bottom area of the tailgate. A drive lever may be pivotally connected to the lever arm and to a bell crank at opposite ends thereof. The bell crank may be connected to a shaft of a rotary gear pivotally anchored to a vehicle body. A rotary damper may be anchored to the vehicle body and include a damper gear connected to a shaft thereof. The damper gear may be rotatably meshed with the rotary gear. Rotation of the tailgate from a closed to an opened position simultaneously rotates the lever arm to move the drive lever and the bell crank to thereby rotate the rotary gear which rotates the damper gear to actuate the rotary damper to reduce an opening speed of the tailgate.

Abstract: A vehicle tailgate movement assist mechanism may include a tailgate configured to rotate between opened and closed positions, and a tailgate cam lever arm fixedly connected to a bottom area of the tailgate. A bell crank may be pivotally anchored at one end thereof to a vehicle body, and a strut may be pivotally anchored at one end thereof to the vehicle body and pivotally connected at an opposite end thereof to the bell crank. With the tailgate cam lever arm, bell crank and strut configured as discussed, rotation of the tailgate from a closed to an opened position simultaneously rotates the tailgate cam lever arm to contact and rotate the bell crank to actuate the strut to reduce an opening speed of the tailgate.

A drive lever may be pivotally connected at one end thereof to the tailgate lever arm and pivotally connected at an opposite end thereof to a bell crank. The bell crank may be pivotally anchored at one end thereof to a vehicle body, and a plunger damper may be anchored to the vehicle body adjacent the bell crank. With the mechanism configured as discussed above, rotation of the tailgate from a closed to an opened position simultaneously rotates the tailgate lever arm to impart movement to the drive lever and the bell crank to thereby contact and actuate a plunger of the plunger damper to reduce an opening speed of the tailgate.
