8、Place the weight of 80 kg on the seat cushion. 5.4.2. Place the weights of 80 kg on both sides of the bench seat respectively. 5.4.3. Set the slider to the forefront position. 5.4.4. Release the locking device, and move the slider to the rearmost position (where the guide rail touches the stopper) i

9、n speed of 0.1 0.3 m/sec. 5.4.5. Release the locking device, and move the seat in forward direction to make the poke slide and is locked in the end position. 5.4.6. Release the locking device, and move the seat to the rearmost position (where the guide rail touches the stopper) in speed of 0.1 0.3 m

10、/sec. 5.4.7. Release the locking device, and move the seat in forward direction to make the poke slide and is locked in the end position. 5.4.8. Repeat the procedure on the front seat for 15000 cycles and on the rear seat for 3000 cycles. Each cycle consists of procedures defined in item 5.2.2 throu

11、gh 5.2.5. 5.5. Test method of durability of the power adjuster systems 5.5.1. Place the weight of 80 kg on the seat cushion. 5.5.2. Place the weights of 80 kg on both sides of the bench seat respectively. 5.5.3. Set the slider to the forefront position. 5.5.4. Reciprocate the slider in full stroke a

12、t DC 12 V voltage. 5.5.5. Supply the power to make the forefront and the rearmost part of the slider contact with the stopper for two seconds or longer. 5.5.6. If the limit switch interrupts the power, skip the procedure in item 5.5.5. EDS-T-4549TEST PROCEDURE OF SEAT SLIDER OPERATION DURABILITY PAG
