3、W14369 & GMW14370. 1. PURPOSE This procedure verifies durability of the folding mechanism during operation of the folding seats. 2. SCOPE All types of sheets with the folding mechanism mounted 3. TEST SAMPLES Minimum three new assemble seat 4. TEST EQUIPMENT AND JIG 4.1. BIW (Body in White) or jig f

4、or fitting seats in vehicle conditions 4.2. Push-pull gauge 4.3. Operation durability tester 5. METHODS AND SPECIFICATIONS OF TEST 5.1. Preparation 5.1.1. Fit the BIW or the seat-fixing jig on the operation durability tester, and then mount a seat on the BIW or the jig. 5.1.2. Set the seat adjuster

5、systems other than the folding mechanism to the position specified in the design standard. 5.2. Test method of operating force 5.2.1. Measure the operating force of the locking device by making use of the pull-push gauge while releasing the locking device. 5.2.2. If there are handles on the seat bac

6、k and the cushion, measure the operating force by making use of the handles while folding the seat. 5.2.3. If there is no handles, measure the operating force at the center of the uppermost position of the seat back and the center of the rearmost position of the cushion while folding the seat. 5.3.
