Abstract
Abstract A child safety seat comprises a base adapted to rest on a vehicle seat, a seat body mounted on the base and a pair of releasable connectors projecting from the base and having a first latch for engagement with a standard anchorage unit associated with the vehicle seat. Each connector is secured to the base by a retractable coupling member having a second latch adapted to block retraction of the coupling member when the coupling member is fully extended. The first latch is coupled to the second latch to allow disengagement of the second latch when the first latch is engaged with a standard anchorage unit.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
99 words
A child safety seat comprising: a base adapted to rest on a vehicle seat, a seat body mounted on the base, a releasable connector projecting from the base and having a first latch for engagement with a standard anchorage unit, a retractable coupling member securing the connector to the base and having a second latch adapted to block retraction of the coupling member when the coupling member is fully extended, and link means coupling the first latch to the second latch to allow disengagement of the second latch when the first latch is engaged with a standard anchorage unit.
Claim 2
Dependent Claim
99 words
A child safety seat comprising: a base adapted to rest on a vehicle seat, a seat body mounted on the base, a releasable connector projecting from the base and having a first latch for engagement with a standard anchorage unit, a retractable coupling member securing the connector to the base and having a second latch adapted to block retraction of the coupling member when the coupling member is fully extended, and link means coupling the first latch to the second latch to allow disengagement of the second latch when the first latch is engaged with a standard anchorage unit.
Claim 3
Dependent Claim
51 words
A child safety seat according to claim 1, further comprising: a pawl mounted on the retractable coupling member and arranged engage with complementary formations on the base to resist protraction of the retractable coupling member, and a manually operable release mechanism for causing said pawl to disengage from said complementary formations.
Claim 4
Dependent Claim
57 words
A child safety seat according to claim 2, wherein said manually operable release mechanism comprises a first cam formation on the pawl, a second cam formation on the retractable coupling member and a cam follower connected to a handle and arranged to engage between said first and second cam formations to cause angular movement of the pawl.
Claim 5
Dependent Claim
35 words
A child safety seat according to claim 3, wherein one of said first and second cam formations comprises an arcuate slot and the other of said first and second cam formations comprises a straight slot.
Claim 6
Dependent Claim
30 words
A child safety seat according to claim 2, wherein the manually operable release mechanism is positioned so as to be inaccessible when the base is positioned on a vehicle seat.
Claim 7
Dependent Claim
35 words
A child safety seat according to claim 2, wherein the second latch is mounted for a predetermined range of angular movement on the retractible coupling member for engagement with a complementary formation on the base.
Claim 8
Dependent Claim
99 words
A child safety seat according to claim 6, wherein the link means comprises a release lever mounted for angular movement on the retractible coupling member and having a stop formation arranged to engage with a complementary formation on the second latch for varying said predetermined range of angular movement in dependence on the orientation of the release lever, a position sensor linked to the release lever and responsive to engagement of the first latch to move the release lever to an orientation in which said predetermined range of angular movement includes an orientation in which the second latch disengages.
Claim 9
Dependent Claim
28 words
A child safety seat according to claim 7, wherein the stop formation comprises a pin and the complementary formation comprises an arcuate slot with the pin engaged therein.
Claim 10
Dependent Claim
30 words
A child safety seat according to claim 7, wherein the position sensor comprises a detent adapted to engage with the first latch thereby to retain it in its engaged position.
Claim 11
Dependent Claim
32 words
A child safety seat according to claim 9, wherein the release lever includes a manually engageable formation for causing movement of the disengagement of the position sensor to release the first latch.
Claim 12
Dependent Claim
41 words
A child safety seat according to claim 7, wherein a second releasable connector has a first latch for engagement with a second standard anchorage unit associated with the vehicle seat, the second releasable connector being secured to said retractable coupling member.
Claim 13
Dependent Claim
41 words
A child safety seat according to claim 2, wherein a second releasable connector has a first latch for engagement with a second standard anchorage unit associated with the vehicle seat, the second releasable connector being secured to said retractable coupling member.
Claim 14
Dependent Claim
35 words
A child safety seat according to claim 1, wherein the second latch is mounted for a predetermined range of angular movement on the retractible coupling member for engagement with a complementary formation on the base.
Claim 15
Dependent Claim
99 words
A child safety seat according to claim 13, wherein the link means comprises a release lever mounted for angular movement on the retractible coupling member and having a stop formation arranged to engage with a complementary formation on the second latch for varying said predetermined range of angular movement in dependence on the orientation of the release lever, a position sensor linked to the release lever and responsive to engagement of the first latch to move the release lever to an orientation in which said predetermined range of angular movement includes an orientation in which the second latch disengages.
Claim 16
Dependent Claim
28 words
A child safety seat according to claim 14, wherein the stop formation comprises a pin and the complementary formation comprises an arcuate slot with the pin engaged therein.
Claim 17
Dependent Claim
30 words
A child safety seat according to claim 14, wherein the position sensor comprises a detent adapted to engage with the first latch thereby to retain it in its engaged position.
Claim 18
Dependent Claim
32 words
A child safety seat according to claim 16, wherein the release lever includes a manually engageable formation for causing movement of the disengagement of the position sensor to release the first latch.
Claim 19
Dependent Claim
41 words
A child safety seat according to claim 14, wherein a second releasable connector has a first latch for engagement with a second standard anchorage unit associated with the vehicle seat, the second releasable connector being secured to said retractable coupling member.
