    I searched and could not find an easier understanding of the entire lever/recliner and how it works. Thanks. A great thing to post.

    Thank you very much.. the seat mechanism went out in my Toyota 4Runner and as this video looks like it was from a Toyota truck of some sort.. it was a total life saver. Thank you.

    This recliner is but one of many designs. This one is a sector gear recliner with a locking pawl. There is the Taumel type rotary gear, German design. Then there is the linear type, which uses one or two cylinders, with plungers. How do I know? I worked at a recliner supplier for automotive seating, ran the life and reliability test lab for several years. I tortured and wore out recliners for many models. Best seat/recliner combination: the basic Recaro. Worst I encountered: the Mitchell bucket, used in circa '90 Suburbans... We called that frame the "lawn chair." Basic performance measurements for recliners: Radial play, recline effort, lift load, handle effort, for basic clocksprung sector types. Rotary wheel effort for Taumel. Static rear, forward torque to failure, and fatigue to rear tests performed. Then there is the life cycle testing, 10,000 cycles minimum is typical. Forward dump tests, also. Then there is the inertia lock forward test, for recliners so equipped. Best rule for design: Keep it simple. We had a recliner that had the dump feature for 2 door, worked great, compare it to one of the high end GM designs... the Cadillac sample we had was ridiculously complicated. They kept adding parts, until it worked. I was Dr. Destructo in that lab. I also designed test machinery that worked the first time I tried them out, unlike certain "engineers" up in the front office. You make it, I will revise a way to break it or wear it out. One last piece of advice: for any pin/v hole wear... Lithium grease. Use on door/hood hinges, etc. Use on latches. I proved it out in the lab.

      P272 They closed the plant in the late 90's. I am retired now, am building a container home, my design. Regarding automotive seating, from what I've seen in later years, is that they are improved. I still don't think the Recaro has been outclassed. BTW I made an office chair from a passenger side bucket, out of a small GM suv, has double telescoping cylinders (linear type recliner), mounted on the base of my previous office chair.

      Cool, thanks for replying back. Good luck with the container house. A guy named Tony Hsieh (Zappos) built a container mall on Freemont Street in Las Vegas, check it out. Your office chair sounds bad ass. I'm searching for seat, springs and magnetic engineers for three patent projects im working on. Figured I'd see if you were still in the biz. Cheers and post that house when you get her done.

    so if the seat is free falling forward and wont stay upright that means the teeth are out of line with the stabilizer plate?

  • @aicram62
    @aicram62 Před 2 lety +1

    Great, now what does one need to have the seat lay all the way flat. And then have the seat lift up to become the back and the former back will be the seat and the chair will be facing the rear?

    I’m trying to convert my tiny Kei car into a camper. The back seats fold completely flat, but I need to fold the front passenger seat completely flat too if I want to lay out comfortably. It unfortunately only folds about 45 degrees.
    If I were to remove the stabilizer plate, which appears to be what stops the seat from folding further, would that possibly allow me to fold my seat completely flat?

      @soco13466 Před 6 lety

      Jacob miner guy Benson What broke? If it is one like in same year Chrysler product, you can have anything from a broken handle spring, which means the seat won't lock in place, or a sheared rivet. Check the lower bracket, upper bracket bolts. Maybe the teeth have been sheared, which can't be repaired.
