EN 15694:2009+A1:2015 (E) 5 Introduction Agricultural and forestry tractors are often equipped with a passenger seat to allow the safe, short-term and occasional transport of a person from the farm to the field. The tractor and cab design is defined by and optimized for various functions and operating conditions. The passenger transport is not a main request and less comfortable conditions are accepted by the market for the benefit of the main purposes. Roll-over protective structures (ROPS) were introduced to improve the safety of the tractor driver during field operations. To allow the protection of the passenger, to consider the specific conditions of tractor design, its intended use and all risks including the risk of roll-over, the standard should satisfy especially the following conditions: — to specify requirements to be applied to all tractors respectively all operations and requirements depending on the intended use respectively operations taking into account the normal use; — to specify performance based requirements corresponding to the state of art and minimizing the necessary changes in tractor design; — to ensure a high level of occupational safety for both – the driver and passenger – during the individual operations; — not to reduce the protection of the driver or passenger against other risks; — to refer to available specifications or standards; — to provide repeatable and reproducible test procedures.

It specifies minimum requirements for space and support, specifies roll-over protective structures (ROPS) test procedures and seat belt requirements, by reference to other standards.

Deflection limiting volume, sequence of tests and acceptance criteria for the passenger seat (see 5.2) B.1 Passenger Deflection Limiting Volume (PDLV) The passenger deflection limiting volume (PDLV) is established using the passenger seat index point (SIPp), as defined in 3.2 according to the dimensions reported in Figure B.1.

Figure B.2 — Rearward, forward and lateral rotation In addition, the upper portion of the PDLV, as illustrated in Figure B.3, is allowed to flex forward and rearward an additional 15° maximum with respect to transversal reference plane. This flexion movement is around a flexion axis (FA) located as reported in Figure B.3.

EN 15694:2009+A1:2015 (E) 12 Thus, the overall possible rearward and forward motions of the PDLV are illustrated in the side views of Figure B.4. The PDLV is allowed to rotate forward, rearward and to each side about the SIPp and to flex forward and rearward about FA in any part of the tests. The SIPp may move during the test due to deflection of the chassis. If this occurs, the PDLV will continue to maintain its relationship with the SIPp.

For its definition, ISO 5353:1995 shall be applied. B.3 Allowable interference B.3.1 General During the ROPS test for agricultural or forestry tractors, a maximum interference between operator clearance zone (OCZ) and passenger deflection limiting volume (PDLV) is allowed. In particular the OCZ, defined in relation to the operator seat index point (SIPo)1, has been divided into three interference zones as follow (Figure B.5): — the first zone extends for 350 mm (plane a in Figure B.5) in longitudinal direction from the back of the operator clearance zone (point G in Figure B.5); — the second zone is enclosed among the end of the previous one (plane a) and a transversal plane (plane b in Figure B.5) located at 400 mm from point B in longitudinal direction;

Key 1 tractor longitudinal median plane Figure B.5 — Interference zones For each of the interference zones previously defined a maximum allowable interference between OCZ and PDLV has been set. The reference interference zone is the one which contains the projection of SIPp on the tractor longitudinal median plane (see Figure B.5). If this projection coincides with one of the division planes (a or b) the reference interference zone should be indifferently one of the two zones sharing the division plane. With reference to Figure B.6 a minimum horizontal distance (A) between SIPp and SIPo shall be evaluated. SIST EN 15694:2012+A1:2016

A tolerance of 5 % should be applied to all dimensions reported in Tables B.1, B.2 and B.3. Reference interference zone, angular deflection () and vertical distance (h) measured at the beginning shall be considered constant during any part of the tests. B.3.3 Reversible driver’s position For tractors with a reversible driver’s position (reversible seat and steering wheel), it is necessary to repeat the interference evaluation procedure also for rearward facing seat position, as described in B.3.2 for forward facing seat position.

Figure B.7 — Interference zone in case of reversible driver's position (left side view) In fact, the OCZ for reward facing seat position will have different interference zones, vertical distance (h) and transversal distance (A) with respect to OCZ for forward facing seat position (see Figure B.7), while the angular deflection () will be the same for both seat configurations because it is defined by the passenger seat and the tractor longitudinal median plane. Applying the interference evaluation procedure to both driver seat positions, the four cases reported in Table B.4 may present.

When operator seat is in rearward position passenger seat usage shall be avoided or tractor rearward functionality shall be limited. SIST EN 15694:2012+A1:2016
