Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A seat comprising a seat member having one lateral side hingedly connected to a stationary structure for pivotal movement between a horizontal position and a certain angular position and having an opposite side, an upstanding backrest having a bottom abutting side resting upon the opposite side of the seat member, and an yieldable latch member rigid with the opposite side of the seat member and hold in a projected latching position by means of the bottom abutting side when the seat member is in said horizontal position, said latch member being resiliently deformable by engagement with the bottom abutting side of the backrest to be released from the latching position during pivotal movement of the seat member.
Claim 2
Dependent Claim
117 words
A seat comprising a seat member having one lateral side hingedly connected to a stationary structure for pivotal movement between a horizontal position and a certain angular position and having an opposite side, an upstanding backrest having a bottom abutting side resting upon the opposite side of the seat member, and an yieldable latch member rigid with the opposite side of the seat member and hold in a projected latching position by means of the bottom abutting side when the seat member is in said horizontal position, said latch member being resiliently deformable by engagement with the bottom abutting side of the backrest to be released from the latching position during pivotal movement of the seat member.
Claim 3
Dependent Claim
37 words
A seat as claimed in claim 1, comprising manually operable means to retract the seat member to said certain angular position to cause the latch member to be deformed during said pivotal movement of the seat member.
Claim 4
Dependent Claim
101 words
A seat as claimed in claim 1, in which said latch member comprises a support member fixed to the opposite side of the seat member and having a portion pivotally movable toward and apart from the opposite side of the seat member, and spring means resiliently urging the pivotally movable portion to said latching position apart from the opposite side of the seat member, and a deformable confinement extending along the outside of the pivotally movable portion and fixed at its periphery to the opposite side of the seat member to confine the pivotally movable portion to a predetermined angular position.
Claim 5
Dependent Claim
73 words
A seat as claimed in claim 3, further comprising a manually retractable belt having one end fixed to the seat member and extending along the outside of said confinement in a direction of pivotal movement of the seat member toward said certain angular position, whereby said latch member is resiliently deformable to pass the bottom abutting side by manual retraction of said belt together with the seat member toward said certain angular position.
Claim 6
Dependent Claim
44 words
A seat as claimed in claim 1, in which said latch member comprises a deformable confinement fixed at its periphery to the opposite side of the seat member and an elastomeric block received in said confinement resiliently biasing the confinement to an expanded state.
Claim 7
Dependent Claim
73 words
A seat as claimed in claim 5, further comprising a manually retractable belt having one end fixed to the seat member and extending along the outside of said confinement in a direction of pivotal movement of the seat member toward said certain angular position, whereby said latch member is resiliently deformable to pass the bottom abutting side by manual retraction of said belt together with the seat member toward said certain angular position.
