Abstract
Abstract In a vehicle seat having a squab pivotally mounted on the vehicle floor adjacent the front of the squab, a normally engaged coupling is connected between the rear of the squab and the floor to prevent forwardly tilting of the squab. An operating device is provided for selectively disengaging the coupling. A normally disengaged coupling is also provided between the rear of the squab and the vehicle floor. Upon deformation of the squab in a forward direction during a collision the normally disengaged coupling will become engaged to prevent forward tilting of the squab.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A vehicle seat comprising a squab having a front end portion and a rear end portion, pivot means having a hinge axis pivotally mounting the front end portion of the squab on a floor of a vehicle passenger compartment, normally-disengaged coupling means mounted on the floor of the passenger compartment and the squab and adapted to be brought into a coupling position as a result of a deformation of the squab in a forward direction from said rear end portion to said front end portion, normally engaged coupling means mounted on the floor of the passenger compartment and the squab and operating means connected to said normally engaged coupling means for selectively moving said normally engaged coupling out of engagement in order to enable the forward tilting of the squab about said hinge axis.
Claim 2
Dependent Claim
134 words
A vehicle seat comprising a squab having a front end portion and a rear end portion, pivot means having a hinge axis pivotally mounting the front end portion of the squab on a floor of a vehicle passenger compartment, normally-disengaged coupling means mounted on the floor of the passenger compartment and the squab and adapted to be brought into a coupling position as a result of a deformation of the squab in a forward direction from said rear end portion to said front end portion, normally engaged coupling means mounted on the floor of the passenger compartment and the squab and operating means connected to said normally engaged coupling means for selectively moving said normally engaged coupling out of engagement in order to enable the forward tilting of the squab about said hinge axis.
Claim 3
Dependent Claim
45 words
A vehicle seat as set forth in claim 1, wherein said front end portion of the squab is disposed in a position generally higher than the rear end portion of the squab relative to the floor in the normal position for use of the seat.
Claim 4
Dependent Claim
48 words
A vehicle seat as set forth in claim 1, wherein said squab includes a generally elongated Z-shaped framework extending between said front end portion and said rear end portion with said front end portion mounted in a position higher than said rear end portion relative to said floor.
Claim 5
Dependent Claim
47 words
A vehicle seat as set forth in claim 1, wherein each of said coupling means is comprised of two complementary elements, one of which is common to both said coupling means and is comprised of a hooked element mounted on one of the floor and the squab.
Claim 6
Dependent Claim
48 words
A vehicle seat as set forth in claim 4, wherein said hooked element is mounted on the floor of the passenger compartment and a catch element is mounted on said squab, said hooked element and said catch element constituting said complementary elements of said normally disengaged coupling means.
Claim 7
Dependent Claim
54 words
A vehicle seat as set forth in claim 4, wherein said hooked element is mounted on the floor of the passenger compartment and a wire loop-like member is pivotally mounted on said squab about said hooked element, said hooked element and said loop-like element constituting said complementary elements of said normally engaged coupling means.
