What Is This Thing Called?
 

For the life me I cannot think of what these are called…those articulating, “swing-arm” clamps which are threaded on one end - with this threaded end fitted with a thumb screw…so when this threaded end is swung into a “receiver plate,” the thumbscrew is then tightened until the appropriate (desired) locking force is achieved. Anyone?

Are you describing Kant Twist clamps?

Toggle Clamp?

Nope (but thanks!).

The receiver plate features a v or u shaped open end, into which the threaded shaft with thumbnut is swung, then the thumbnut tightened against the bottom flange of the receiver plate. Hmmm...maybe I'll draw a picture and post it.

I think that'll help a lot.

Hold down clamp?

Here it is! I knew I had something around someplace with this type of locking mechanism…here in the form of my old Leitz tripod leg-clamp accessory:

But what I need is something which operates on this principle, to replace a “fixed adjustment” hook and eye scenario. Here is my application...for our cute/lovable (and sometimes naughty) rescue-up, Lena:

I have crafted, from plywood, foam, and faux leather, a doggie seat, which fits into the otherwise rather uncomfortable rear seat-wells of my 944:

The doggie seat sets upon two carefully shaped plywood panels, each affixed via. existing seatbelt bolts. Currently, the seat is held down with two hook and eye locks - which to work effectively need to be adjusted exactly, but the adjustment of the whole “system” tends to deviate over time, and it would be great if I could tighten things down a bit more.

Here’s the kicker: yes, I could simply install angle brackets to make this more solid…but I like the idea of being able to quickly unclip/remove the doggie seat, thus the need for a mechanism which allows such easy removal, and also allows for some adjustment to clamping force.

At any rate…any ideas? Thanks!

How about this or a couple of Lindells My Pillows?

I think that is called a split block clamp.
For the pup, why didn't you just fold down the rear seat backs?

I use this. It goes from truck to car. He's very comfortable in it like a crate. Holds him in place too but he's never ridden in the 911. He doesn't like getting tossed around violently
