ABSTRACT:
An improved safety impact headrest protector device which can be mounted to the inside of rear and side windows of vehicles including cabs, trucks, station wagons and the like for protecting the head of the driver and/or passenger(s) against injury. The safety impact headrest includes a cushion device having an overall six sided rectangular box-like configuration. The cushion device includes three triangular tubular members each formed of transparent flexible fluid impermeable material. The triangular tubular members include a rear equilateral configured tubular member including a back side and first and second angular sides; a first right angle configured tubular member with the elongated side member equal to and attached to the forward first angular side of the rear tubular member; and a second right angle configured tubular member with the elongated side member equal to and attached to the second angular side of the rear tubular member. A valve is attached to each of the three tubular members for controlling the amount of fluid pressure value in each tubular member. A fluid expelling device is attached to the upper surface of the rear center tubular member which provides for a selected amount of fluid to expire from the rear tubular member at a controlled exponential at the beginning of an impact upon the headrest protector device to protect the user's head. The headrest protector device includes an attaching device for attaching the headrest device in different locations and upon different surfaces.
