And a bumper mechanism that is interposed between the body bracket and the bumper bracket and that displaces the bumper bracket to the projecting position to widen the gap between the bumper body and the vehicle body before lowering the bumper body. And a sliding mechanism that supports the bumper bracket that holds the body so that the protruding bracket can linearly move up and down. That bumper lifting device.

2 The bumper body is arranged so as to form the opening edge of the luggage compartment opening, and the bumper body is inverted and supported between the expanded position where the bumper body is lowered so that the luggage room opening edge is lowered and the raised normal position. A bumper lifting device for fixing to a vehicle body, a protruding bracket supported on the outside of the body bracket, and a bumper mounted between the body bracket and the protruding bracket before the bumper body is lowered. A protrusion mechanism that temporarily displaces the protrusion bracket to the protruding position to widen the gap between the body and the vehicle body, a sliding mechanism that supports the bumper bracket that holds the bumper body so that the protrusion bracket can move up and down linearly, and a bumper bracket when protruding. Lowering prevention latch that holds the It consists in bumper elevator apparatus characterized by comprising a lock mechanism having a retraction suppression latch for holding the bracket projecting to over body does not retract.

"Operation" While the vehicle is running, the bumper body is held in the raised normal position to protect the vehicle body.

When loading or unloading luggage into or from the luggage compartment, lowering the bumper body to the expanded position forms the opening edge of the luggage compartment opening, so the opening edge of the luggage compartment opening lowers and lowers easily. Can be taken in and out. Since the luggage compartment opening expands, large items can be easily loaded.

When the bumper body is moved up and down, in the bumper lifting device, the body bracket and the protruding bracket fixed to the bumper body are displaced, and accordingly, the bumper body is projected or lifted.

The bumper body in the normal position is first displaced by the ejection mechanism. When the protruding bracket is displaced to the projecting position, the bumper body projects, and the gap between the bumper body and the vehicle body widens so as not to interfere with each other when moving up and down. At this time, the bumper bracket that supports the bumper body is held so as not to be lowered by the lowering prevention latch of the lock mechanism.

When in the protruding position, the bumper bracket is released from the lowering prevention latch of the lock mechanism.

Then, when the bumper bracket is lowered by the sliding mechanism, the bumper body is lowered to the expanded position as described above, and the opening edge of the luggage compartment opening is lowered and lowered. During the descent, the protruding bracket is held by the retracting prevention latch so as not to retract, and the bumper body does not inadvertently retract and interfere with the vehicle body.

The bumper body in the expanded position is displaced in the opposite direction by the sliding mechanism and returns toward the normal position.

When the bumper bracket is displaced through the sliding mechanism and the bumper body is completely raised, the protruding bracket is released from the retracting restraint latch of the lock mechanism.

If the ejecting mechanism is operated in reverse, the ejecting bracket retracts, the bumper body retracts, and the gap between the bumper body and the vehicle body becomes a minimum normal position to stop. During the retracting operation, the bumper bracket is held by the lowering prevention latch so as not to be lowered.
