[Risk of injury to children's fingers in power-operated motor vehicle windows].

BACKGROUND

This study examines the dimensions of children's fingers and the risk of jam injuries in a 4-mm gap between glass and gasket of power-operated motor vehicle windows.

MATERIAL AND METHODS

The diameter of the proximal, middle, and distal phalanx and of the proximal and distal interphalangeal joint of each finger of the right hand of 160 children was measured in a cross-sectional investigation. Six different drawings in cross section of gaskets and glass window panes of current motor vehicle side door windows at a vertical gap of 4 mm were drawn in correct proportion. The larger actual width of the oblique gap between window glass and gasket was measured and related to the diameters of children's fingers.

RESULTS

Almost all fingers and joints fit in the largest actual gap of 18 mm between glass and gasket of one seal design.

CONCLUSION

The European guideline 74/60/EWG specifications currently pertaining to closing force restriction do not eliminate the risk of potentially serious injury to children's fingers in motor vehicle power windows.
