Try decelerating quickly(ie: putting on the brakes) while doing 30mph (48kph) or so, and pull on the seatbelt. It should lock. There is a mechanism which senses deceleration to tighten the belt. Like when you stop suddenly from hitting another object. Quote Link to comment Share on other sites More sharing options...
qha_vn Posted November 19, 2007 Author Share Posted November 19, 2007 thanks, i will find somewhere and try a hard brake. by the way, do your seat belts lock on quick pull? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted November 20, 2007 Share Posted November 20, 2007 It will only lock them up if the weight at the bottom of the belts are shifted out of its center. It is a small pendulum weight that locks when ever weight transfer is detected. Quote Link to comment Share on other sites More sharing options...

Every seat belt retractor has a centrifical "brake/clutch" such the rapid unspooling of the belt will be quickly stopped. If yours doesn't then something is wrong.

I tried tugging on my Lex and as wwest mentioned, it locks up with a rapid pull. Both sides worked the same. Then I went to my Chrysler Town and Country. No lock up on either side despite very quick pull. And yet it locks when I hit the brakes. I am intrigued. Quote Link to comment Share on other sites More sharing options...
qha_vn Posted May 9, 2008 Author Share Posted May 9, 2008 i did try braking hard at 40kph and noticed that the seat belt was locked. so the locking mechanism works only in sudden stop unlike normal belt which gets locked on quick pull Quote Link to comment Share on other sites More sharing options...
hav2laf2 Posted May 9, 2008 Share Posted May 9, 2008 What about the opposite? My front passenger seatbelt locks all the time. It allows you to pull it out to fasten, but then develops a chokehold on you. Thank you. Quote Link to comment Share on other sites More sharing options...
