CopyrightInternational Oorganizatio for Standardization Price based on 2 pages without license from IHS Not for Resale FOREWORD ISo (the International Organization for Standardization) is a worldwide federation of national standards institutes (IsO Member Bodies). The work of developing International Standards is carried out through IsO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up 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. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the iso Council. International Standard IsO 3409 was drawn up by Technical Committee ISO/TC 22, Road vehicles, and circulated to the Member Bodies in February 1974. It has been approved by the Member Bodies of the following countries : Austria Iran Sweden Belgium Italy Switzerland Buigaria Japan Thailand Mexico Turkey Chile Netherlands United Kingdom Czechoslovakia Egypt, Arab Rep. of Poland U.S.A. Finland Portugal U.S.S.R. France Romania Yugoslavia Germany South Africa, Rep. of Hungary Spain The Member Bodies of the folowing countries expressed disapproval of the document on technical grounds : Australia Brazil @ International Organization for Standardization, 1975 : Printed in Switzerland Copyright International Organization for Standardization Not for Resal ISO 3409-1975 (E) INTERNATIONAL STANDARD Passenger cars --- Lateral spacing of foot controls 1 SCOPE point A to the R point (the rearmost normal driving position) (see figure 1). This International Standard lays down required characteristics concerning the positions and distances necessary to ensure' sufficient ateral spacing for the operation of foot controls. 4 REQUIRED CHARACTERISTICS 4.1 Arrangement of controls 2 FIELD OF APPLICATION As observed from the driver's position, the controls shall be This International Standard applies only to the accelerator, in the following order from left to right : clutch pedal, service brake and clutch pedals (defined in 3.1, 3.2 and 3.3) service brake pedal and accelerator pedal. for passenger cars and derivatives. 4.2 Distance between two pedals 3 DEFINITIONS The minimum distance shall be measured between the For the purpose of this International Standard the projections of the two pedals onto the reference plane P following definitions apply : (defined in 3.8) (see figure 2). A minimum distance shall be prescribed between 3.1 accelerator pedal : The driver-operated portion of the device whose primary function is to vary the engine power the accelerator and service brake pedals, and output. the service brake and clutch pedals. 3.2 service brake pedal : The foot-operated portion of the 4.3 Distance between the clutch pedal and the fixed part primary device designed to decelerate and stop the vehicle. of the body 3.3 clutch pedal : The foot-operated portion of the The minimum distance shall be measured between the mechanism designed to engage (clutch) or disengage projection of the clutch pedal onto the reference plane P (declutch) the vehicie power unit from the transmission and and the section given by this plane with the trim panel (see road wheels. figure 2). 3.4 transverse plane : A plane perpendicular to the median 4.4 Minimum lateral space for the actuation of one pedal longitudinal plane
