Introduction
Introduction
The strength of the rear seat needs to be tested to protect the occupants against displacement of luggage during vehicle impact. The rear seat must be able to withstand a static test load simulating luggage impact. ECE-R17 is one of the tests that provide the assurance of sufficient strength resistance of the rear seat.
The luggage retention tool creates a plane for luggage masses to slide on and positions the luggage blocks of type-1 and type-2 if the seat-back is fitted with a head restraintis according to ECE-R17 specification. The tool will also set up the analysis as per the regulation.
The following figure shows "Main input" panel of the tool:
The following options are available on the main input panel:
| Settings file | A settings file may be read or written which will save specifying inputs repeatedly. The reading/writing of a settings file is optional. |
| R-point | R-point is the relative location of the seated dummy's hip point when the seat is set in the rearmost and lowermost seating position. |
| Create bottom plate | Select if you wish to create a bottom rigid plate part on which vehicle will be mounted. A longitudinal horizontal load shall be applied to the bottom rigid plate. |
| Select bottom plate | Use this option to select an already existing bottom rigid plate in the model on which vehicle is mounted. A longitudinal horizontal load shall be applied to the bottom rigid plate. |
| Ceate bndy prescribed motion | Select if you wish to create a *BOUNDARY_PRESCRIBED_MOTION on the bottom rigid plate. |
| Blockage part set | Select a part set that luggage blocks should not impinge on |
| Seatback+Bottom part set | Select a part set consisting of PART(s) that makes up the rear seat excluding head restraint components |
| Head rest part set | Select a part set comprising of head restraint parts. |
| Use partitioning system | Select if the vehicle has a partitioning system (for examplke a net) which prevents luggage from sliding. |
| Partition part set | Select a part set consisting of partitioning systems including net part. |
| Position TYPE-2 Blocks | Select if you wish to position TYPE-2 test blocks. By default, it will be OFF. |
| Units | Specify units system of the selected model. |
