Free Motion Headform Position Kits

FMH Positioning Tools

Available Models

Features

  • TE‐110‐6GG: The standard positioning kit consists of a clear plastic head mounted on an extruded aluminum beam of a length equal to the accelerator stroke. The beam is mounted to a back plate simulating the FMH back plate with a ¼ inch (6.35 mm) diameter pin to interface with a hole in the accelerator rod for positioning. The unit has a vertical line laser mounted on top projecting upward. The forehead is scribed with a target pattern following the requirements of FMVSS 201. A digital protractor is mounted to the underside of the aluminum beam and there is a bubble level for cross axis angle zeroing.
  • TE-110-ADJ-6GG: The adjustable positioning kit consists of a clear plastic head mounted on an extruded aluminum beam which has adjustable side plates to set the overall length for different accelerator strokes. The side plates are mounted to a back plate simulating the FMH back plate with a ¼ inch (6.35 mm) diameter pin to interface with a hole in the accelerator rod for positioning. In addition to the vertical laser the unit has a horizontal spot laser, projecting forward. It is mounted on a slide allowing vertical and horizontal motion. The forehead has the same target area scribed on it that is on TE-110-6GG. In addition twenty holes, located on a 12.5 mm square grid pattern, are drilled through the target area to allow the spot laser beam to exit the headform. A second bubble level is included.

Method of Use

  • TE‐110‐6GG: The positioning kit is attached to the front of the accelerator and is held in place by magnets. The extruded beam simulates the stroke. The vertical line laser is switched on and is used to align the unit with respect to the centerline of the vehicle. The head is aimed at the target in the car which must appear inside the scribed target area on the face of the clear plastic head. The test technician looks through the side or back of the head to make the alignment. The lateral impact angle is adjusted and indicated by the protractor. The accelerator is fixed in position allowing for at least 25 mm of free flight for the head. The kit is then replaced by the FMH to conduct the regulated test.
  • TE-110-ADJ-6GG: The positioning kit is mounted the same as the TE-110-6GG; its overall length may be adjusted as noted above. The lasers are switched on. The vertical line laser is used to align the unit with respect to the centerline of the vehicle. The horizontal spot laser beam is adjusted to shine through a selected hole in the front of the head and the spot is aligned with the desired target in the vehicle. The rest of the procedure is the same as above.

Application

TE‐110‐6GG is primarily for GM applications and TE‐110‐ADJ‐6GG is primarily for other applications. The length of the adjustable unit may be fixed. The beam length may be set at stroke, plus free flight (~25 mm), if the clear head is to be put into contact with the target inside the car. It may be set shorter for non‐contact aiming. The inclusion or exclusion of the free flight length is not as important if the accelerator unit can be retracted a calculated amount between aiming and final set up for the test.
