plane seat

Voorbeeldzinnen

1. Suddenly the plane begins to rock and the seat belt signs come on.
2. Section C Trace of vertical median plane of seat
3. Trace of vertical median plane of seat r R
4. a horizontal plane passing through a point 90 – av below the seat index point;
5. The seat reference point (S) shall be the point in the central longitudinal plane of the seat where the tangential plane of the lower backrest and a horizontal plane intersect.
6. The side loading shall be applied horizontally, in a vertical plane perpendicular to the tractor’s median plane passing 60 mm in front of the seat index point, the seat being at the mid-position of the longitudinal adjustment.
7. For individual seats, the centre plane of the seat coincides with the centre plane of the occupant. For other seats, the centre plane of the occupant is specified by the manufacturer;
8. an inclined plane, perpendicular to the reference plane which meets the plane defined in 1.6.2.3 above at its rearmost edge and rests on the top of the seat back rest;
9. by a transverse vertical plane through the rearmost upper point of the seat back and by a transverse vertical plane 280 mm in front of the foremost point of the uncompressed seat cushion, measured in each case at the median vertical plane of the seating position.
10. All lines, including the projection of the reference line, shall be drawn in the vertical median plane of the seat or seating position concerned, the intersection of such plane with the seat determining the contour of the head restraint and of the seat-back (see figure 1 of Annex 4 to this Regulation).
11. “Forward-facing seat” means a seat which can be used whilst the vehicle is in motion and which faces towards the front of the vehicle in such a manner that the vertical plane of symmetry of the seat forms an angle of less than + 10o or - 10o with the vertical plane of symmetry of the vehicle;
12. For tractors with a reversible driver’s position (reversible seat and steering wheel), the point of impact shall be in the plane at right angles to the median plane and passing at the midpoint of the segment joining the two seat index points defined by joining the two different positions of the seat.
13. an inclined plane perpendicular to the reference plane, parallel with and 400 mm above the reference line, extending backwards to the point where it intersects the vertical plane which is perpendicular to the reference plane and which passes through a point (140 + ah) mm rearward of the seat index point;
14. in the case of sideways facing seats, the forward part of the cylindrical gauge must reach at least the transversal plane which coincides with a vertical plane passing through the centre of the forward seat (Annex 4, Figure 7);
15. Where the horizontal plane(s) passing through the ‘H’ point of the lowest front and rear seats do not coincide, then a vertical plane perpendicular to the vehicle's longitudinal axis shall be determined, passing through the front seat ‘H’ point.
