Sunday's incident occurred as Red Bull driver Webber was leaving the pits following a tyre change that had taken longer than usual.
The Australian was released without the right rear wheel being properly secured and after it came free of the car it bounced into Allen, striking the Briton from behind.
The FIA also announced that it will seek an immediate change to regulations so that all team personnel working on cars during pit stops wear head protection, and that the speed limit in the pits is reduced from 100 kmh to 80 kmh.
