Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO could not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

5 Recommendations
5.1 General

It is recommended to start with the positioning of the rear outboard dummies to facilitate the placement

of all dummies.
5.2 Position of the rear seats
5.2.1 Rear seats

Longitudinal seat adjustment should be positioned according to the design longitudinal position for

Hybrid III 5th percentile female dummy defined by car manufacturer. If no design position is available,

the seat should be adjusted as close as possible to the mid-track position.

Vertical seat adjustment should be positioned in the design position defined by car manufacturer. If no

design position is available, the seat should be adjusted as close as possible to the lowest position.

If pitch angle can be adjusted independently, it should be adjusted according to the design position

defined by car manufacturer. If no design position is available, it should be as close as possible to the

mid-angled position.
In absence of any manufacture specifications the default procedure should be:

1) The seat control that primarily moves the seat vertically should be used to adjust the seat reference

point to the upper most vertical location.

2) The seat control that primarily moves the seat fore-aft should be used to adjust the seat reference

point defined to the rear most location.

3) The range of angles of the seat cushion pitch referring to the line and using only the control(s) that

primarily adjust(s) the cushion pitch should be determined and recorded, and the set cushion pitch

should be as close as possible to the mid-angle.

4) The seat control that primarily moves the seat vertically should be used to adjust the seat reference

point to the lowest vertical location. A verification that you are still at the rearmost seat track

location should be conducted. The X position should be recorded.
5) The seat control that primarily moves the seat fore-aft to adjust the
