Seatbelt grip
Also known as Seatbelt Control — the canonical term used on this site.
Training background: common abbreviation — refers to the grip rather than the full position
Shorthand for the seatbelt-style back arm configuration
Seatbelt grip is the shorthand label for the seatbelt control — the back-position arm configuration in which one arm passes over the opponent’s shoulder and the other under the opposite armpit, with the hands meeting on the chest.
Etymology. The “seatbelt” metaphor compares the diagonal arm configuration to the diagonal restraint of a car seatbelt across the torso — same diagonal line, same restraining function. “Grip” attaches to the term in instructional vocabulary to distinguish the arm-position-and-hand-connection from the broader back position the configuration enables. The shorthand “seatbelt” alone is also widely used; “seatbelt grip” predominates when the writer wants to emphasise the grip configuration specifically rather than the back-control context generally.
Mechanics. The closed arm loop between the attacker’s hands is the prerequisite for back-position control — the connection allows the attacker to transfer weight to the back, generate chest pressure for strangulation threats, and prevent the opponent from rotating out of the back exposure.
Cross-reference. “Over-under grip” is the descriptive name for the same configuration. Full mechanical coverage on Seatbelt Control.
