A kind of device of the determination head contact point that experiment is whipped for automobile rear seat
Technical field
The invention belongs to vehicle safety experimental technique field, it is related to a kind of being whipped for automobile rear seat to test really
Determine the device of head contact point.
Background technology
Nowadays, the security performance of automobile is increasingly valued by people, more and more comprehensive vehicle safety performance evaluation
Standard starts to be implemented.When occurring to investigate rear-end impact, back seat is to the protective value of heel row occupant, European new car
Assessment routine (European New Car Assessment Programme, Euro NCAP) is added in newest version
Heel row whips the evaluation rule of experiment.Because Euro NCAP have higher authoritative in the world, back seat whips examination
The evaluation tested gradually will be paid attention to by each vehicle producer.
Whipping for back seat is tested based on static measurement, and the rear gap after heel row passenger riding is investigated respectively
And effective depth (Effect ive Height) (Backset).In the measurement process in rear gap, heel row occupant is determined
Head is a most important step with the contact point of back seat headrest, and at present, commonly used approach is according in Euro NCAP
The step of, first calculated, the theoretical level of contact point is obtained, then the point of corresponding height is found on headrest, so that it is determined that connecing
Contact.Because each vehicle has a different parameters, and backrest angle after putting every time is also different, if all entered to measurement every time
Row is calculated and finds contact point again, will make the inefficiency of experiment, accordingly, it would be desirable to a kind of experiment work that can quickly determine contact point
Tool, improves operating efficiency.
The content of the invention
The above mentioned problem that the present invention exists for existing technology, there is provided a kind of to whip experiment for automobile rear seat
Determine the device of head contact point, the technical problems to be solved by the invention are:How to realize efficiently detecting automobile rear whip
