Head excursion first. Except when testing using Q6 or Q3 dummy where the value in relation to the FD plane is 840 mm. In the case of contact of such an Enhanced Child Restraint System with the 100 mm diameter bar and all injury assessment and dummy head displacement criteria are met, there shall be one further dynamic test (front impact) with the heaviest dummy intended for the given range of size indication and without the 100 mm diameter bar; the requirements for this test are that all criteria other than forward displacement shall be met.

Head excursion no part of the head of the dummy shall pass beyond the planes FD, FG and DE, as shown in figure 2 below. This shall be judged up to 300 ms or the moment that the dummy has come to a definitive standstill whatever occurs first. In the case there is a contact of such an Enhanced Child Restraint System with the 100 mm diameter bar and all injury assessment and dummy’s head displacement criteria are met, there shall be one further dynamic test (front impact) with the heaviest dummy intended for the given range of size indication and without the 100 mm diameter bar; the requirements for this test are that all criteria other than forward displacement shall be met.
Head excursion no part of the head of the manikin shall not pass beyond the planes FD, FG and DE, as shown in Figure 4 below. This shall be judged up to 300 ms or the moment that the manikin has come to a definitive standstill whatever occurs first. In the case there is a contact of such a child restraint with the 100 mm diameter bar and all performance injury assessment and manikin’s head displacement criteria are met, there shall be one further dynamic test (front impact) with the heaviest dummy intended for such child restraint the given iSize indication and without the 100 mm diameter bar; the requirements for this test are that all criteria other than forward displacement the criteria of paragraph 7.1.4.2. (child restraint integrity) and paragraph 7.1.4.4.1.2.1. (head exposure) are met. Remark: now from the point of view that a distance from Cr point to dashboard of 700 mm will be an accepted measure, it should be safeguarded that front passenger car seats can offer this space (after normal adjustment of the seat).
