Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
262 words
A vehicle bonnet assembly including a bonnet (11), said bonnet (11) being hinged to the vehicle body adjacent a first edge (12) transverse to the longitudinal axis of the vehicle and having releasable latch means (16) adjacent a second edge (15) transverse to the longitudinal axis of the vehicle, the bonnet (11) being hinged to the vehicle body (13) by means of a hinge assembly (14), which is arranged such that when the bonnet (11) is closed, upon rearward movement of the bonnet (11) in response to an impact above a predetermined magnitude being applied to the leading edge (12) of the bonnet (11), the bonnet (11) is lifted, the bonnet (11) being pivoted between an open and a closed position about the pivotal connection of the hinge assembly (14) to the vehicle body (13) or bonnet (11), characterised in that the hinge assembly (14) comprises a first link (20) pivoted intermediate of its extremities to either the vehicle body (13) or bonnet (11) and second and third links (25, 30) pivoted at one end, each to a different end of the first link (20), and at their other ends to the other of said bonnet (11) or vehicle body (13), the links (20, 25, 30) being arranged such that upon said rearward movement of the bonnet (11), the bonnet 11 is lifted by said links (20, 25, 30), said pivotal movement of the bonnet (11) between an open and a closed position being made about the pivotal connection of the first link (20) to the vehicle body (13) or bonnet (11).
Claim 2
Dependent Claim
74 words
A vehicle bonnet assembly according to Claim 1 characterised in that the bonnet (11) is hinged adjacent its leading edge (12) means (40; 46, 47; 50, 53) being provided adjacent the trailing edge (15) of the bonnet (11) to lift the trailing edge (15) of the bonnet (11) as the bonnet (11) moves rearwardly in response to an impact above a predetermined magnitude being applied to the leading edge (12) of the bonnet (11).
Claim 3
Dependent Claim
109 words
A vehicle bonnet assembly according to Claim 2 characterised in that the latch means (16) comprises a latch arm (40) pivotally attached at one end to the vehicle body (13) or bonnet (11), a latch pin (43) being provided at the other end of the latch arm (40) for engagement of a latching mechanism (44), the latch arm (40) pivoting about the latch pin (43) to lift the trailing edge (15) of the bonnet (11) when the bonnet (11) moves rearwardly in response to a load applied to the leading edge (12), the pin (43) being releasable from the latch mechanism (44) to permit opening of the bonnet (11).
Claim 4
Dependent Claim
24 words
A vehicle bonnet assembly according to Claim 3 characterised in that the latch arm (40) comprises a pair of links (46, 47) pivotally interconnected.
Claim 5
Dependent Claim
56 words
A vehicle bonnet assembly according to Claim 4 characterised in that spring means biases the links (46, 47) to an open position, means (45) being provided to maintain the links (46, 47) in a closed position until a load in excess of a predetermined magnitude is applied to the leading edge (12) of the bonnet (11).
Claim 6
Dependent Claim
28 words
A vehicle bonnet assembly according to Claim 4 or 5 characterised in that means is provided to maintain the links (46, 47) in their open position once opened.
Claim 7
Dependent Claim
127 words
A vehicle bonnet assembly according to Claim 2 characterised in that the latch means (16) comprises an arcuate track (50) mounted on the body (13) of a vehicle, a latch pin (53) being mounted on the vehicle bonnet (11) for engagement of the track (50) as the bonnet (11) is moved between its open and closed positions, a latching mechanism (54) being provided for engagement of the pin (53) when it is at the lower end of the track (50), said track (50) being arranged such that when the bonnet (11) moves rearwardly in response to a load applied to the leading edge (12) of the bonnet (11), the pin (53) will ride up the track (50) to lift the trailing edge (15) of the bonnet (11).
Claim 8
Dependent Claim
48 words
A vehicle bonnet assembly according to any one of the preceding claims characterised in that means (45) is provided to prevent movement of the hinge assembly (14) and/or latch means (16) until the load applied to the leading edge (12) of the bonnet (11) exceeds a predetermined magnitude.
Claim 9
Dependent Claim
57 words
A vehicle bonnet assembly according to Claim 8 characterised in that one or more shear pins (45) are provided on the hinge assembly (14) and/or latch means (16) to prevent movement of the hinge assembly (14) and/or latch means (16) until the load applied to the leading edge (12) of the bonnet (11) exceeds the predetermined magnitude.
Claim 10
Dependent Claim
60 words
A vehicle bonnet according to Claim 8 characterised in that one or more of the pivots (22, 26, 28, 31, 32, 42) of the hinge assembly (14) or latch means (16) are torque loaded to prevent relative movement of the components pivoted thereby, until the load applied to the leading edge (12) of the bonnet (11) exceeds the predetermined magnitude.
Claim 11
Dependent Claim
38 words
A vehicle bonnet assembly according to any one of the preceding claims characterised in that the links (20, 25, 30; 40; 46, 47) of the hinge assembly (14) and/or latch means (16) are resiliently biased by spring means.
