Automatic moving apparatus for pre-crash headrest
First Claim
1. An automatic moving apparatus for a pre-crash headrest, comprising:
- a collision prediction sensor provided on a rear of a vehicle to predict a rear-end collision;
a control unit comparing a value measured by the collision prediction sensor and input to the control unit, with a reference value stored in the control unit, and outputting a control signal when it is determined that the value measured by the collision prediction sensor is higher than the reference value; and
a headrest moving unit moving a headrest unit toward a passenger'"'"'s head before the headrest unit comes into contact with the passenger'"'"'s head when the control signal is input from the control unit to the headrest moving unit, and comprising;
a stay rod connected at an upper end thereof to the headrest unit, both sides of the stay rod being placed in a vertical direction;
tilting device tilting the stay rod forwards or backwards relative to a seatback in response to the control signal of the control unit, thus making the headrest unit come closer to the passenger'"'"'s head; and
vertical moving device moving the stay rod in a vertical direction in response to the control signal of the control unit so that an uppermost end of the headrest unit is not lower than the passenger'"'"'s head.

Abstract
An automatic moving apparatus may include a collision prediction sensor, a control unit comparing a value measured by the collision prediction sensor, with a reference value stored in the control unit, and outputting a control signal when it may be determined that the value measured by the collision prediction sensor is higher than the reference value, and a headrest moving unit moving a headrest unit toward a passenger'"'"'s head before the headrest unit comes into contact with the passenger'"'"'s head, and including a stay rod connected to the headrest unit, both sides of the stay rod being placed in a vertical direction, tilting device tilting the stay rod forwards or backwards relative to a seatback in response to the control signal of the control unit, and vertical moving device moving the stay rod in a vertical direction in response to the control signal of the control unit.
