In the case where negative results are recorded during one of these visits, the competent authority shall ensure that all necessary steps are taken to re-establish the conformity of production as rapidly as possible. If the feet change position, they should be allowed to remain in that attitude for the moment.
Seat, Belt & Anchorage Test System | ECE-R14, ECE-R80 & FMVSS
The force F shall be determined by the following formula: C to ensure that the seat material reaches room temperature. Co-ordinates of “R” point X Y Z The alignment of the sight buttons shall be maintained; Designated seating position: The T-bar must therefore be restrained by applying an appropriate lateral load during the rocking motions.
PURPOSE The procedure described in this annex is used to establish the “H” point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer. The co-ordinates of the “H” point are measured with respect to the three-dimensional reference system; The actual torso angle is read at the back angle quadrant of the 3 DH machine with the probe in its fully rearward position; If a re-run of the installation of the 3 DH machine is desired, the seat assembly should remain unloaded for a minimum period of 30 min prior to the re-run.
For individual seats, the centreplane of the seat coincides with the centreplane of the occupant. Date of report issued by that service: Apply lower leg and thigh weights and level the 3 T80 machine; Tilt the back pan forward against the forward stop and draw the 3 DH machine away from the seat-back using the T-bar.
Other designated seating dce A line through the “H” point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat; Adjust d80 feet and leg positions of the 3 DH machine as follows: The seat anchorages provided in the vehicle and intended to be t80 with the seats indicated in paragraph 1. This device is described in appendix 1 to this annex; “‘H’ point” means the pivot centre of the torso and thigh of the 3 DH machine installed in the vehicle seat in accordance with paragraph 4 below.
They shall be able to pivot in a horizontal plane. Structure, shape, dimensions and materials of the load bearing parts; Types and dimensions of the seat back adjustment and locking system; Dimensions, structure and materials of the attachments and supports e. For other seats, the centreplane of the occupant is specified by the manufacturer; “Three-dimensional efe system” means a system as described in appendix 2 to this annex; “Fiducial marks” are physical points holes, surfaces, marks or indentations on the vehicle body as defined by the manufacturer; “Vehicle measuring attitude” means the position of the vehicle as defined by the co-ordinates of fiducial marks in the three-dimensional reference system.

China us plastic seats China plastic seat kids China stadium plastic seats. Where a seat consists of more than one seating position, the forces corresponding to each seating position shall be applied simultaneously and there shall be as many upper and lower forms as seating positions.
China hard plastic seat China plastic seat and back China seat plastic seat shell. SCOPE This Regulation applies to vehicles constructed for the carriage of more than sixteen passengers, in addition to the driver and crew, in respect of: You accept customized products or not?
The value of t1 and t2 are expressed in seconds. When each foot is placed back in the down position, the heel is to be in contact with the structure designed for this; Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of the back pan sufficient to level the 3 DH machine’s seat pan on the seat; 4.
The maximum displacement of the central point of application of each of the forces prescribed in paragraph 3. Where possible the left foot shall be rr80 approximately the same distance to the left of the centreplane of the 3 DH machine as the right foot is to the right.
This footing shall be described on the communication form. According to the products. The application for approval of a seat or a vehicle shall be accompanied by the following d80 in triplicate and the following particulars: Two spirit levels orient the device in space.

The second digit is a capital letter which designates the location of the seating position in a row, as viewed in the direction of forward motion of the vehicle; the following letters shall be used: Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is obtained.
Carefully return the back pan to the seat-back and check the two spirit levels for zero position. The line passing through the “H” point sight buttons shall be maintained perpendicular to the longitudinal centreplane of the seat; If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move the left foot until it is supported.
An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.

Maintain the 3 DH machine level; Tilt the back pan forward to release the tension on the seat-back. Seat submitted for approval on: ECE R80 Certified plastic bus seat city bus seat plastic seat for bus.
D80 7 – Determination of acceptability criteria Then carefully return the back pan to the seat-back. The “H” point is located in the centre of the centreline of the device which is between the “H” point sight buttons on either side of the 3 DH machine.
Once determined in accordance with the procedure described in paragraph 4, the “H” point is considered fixed in relation to the seat-cushion structure and to move with it when the seat is adjusted; “‘R’ point” or “seating reference point” means a design point defined by the vehicle manufacturer for each seating position and established with respect to the three-dimensional reference rce 2.
Brief description of the seat type, its attachment fittings and its adjustment, displacement and locking systems including the minimum distance between fitting points: If the seat occupant s is are correctly retained by the seat s in front of him them.
Measurements in the femur of the manikin The axial conpression force shall be measured with a CFC of No part of the seat, the seat mountings or the accessories becomes completely detached during the test; The seat remains firmly held, even if one or more anchorages is partly detached, and all the locking systems remain locked during the whole duration of the test; After the test no structural part of the seat or accessories has any fracture or sharp or pointed edges or corners likely to cause any bodily injury.
ecr Measurements to be made on manikins The readings of the measuring devices shall be recorded through independent data channels of the following CFC: F is given in N and i represents the number of seating positions of the seat for which the rce to be tested are to be approved.
The anchorage on the testing platform provided for the test seat s shall be identical to or have the same characteristics as that used in vehicle s in which the seat is intended to be used. If the seat occupant s is are not seriously injured. Location of approval mark on the vehicle: Quadrants are incorporated in the lower leg segments to measure knee angles.
