Abstract
Abstract A vehicle including a hood member mounted thereon for swinging movement relative thereto about a forward axis between raised and lowered position has a striker mounted on the hood member, a retaining lever pivotally mounted on the vehicle and a frangible pin connection between the vehicle and retaining lever maintaining the latter in a fixed orientation relative to the former. In the normal lowered position of the hood member, rearward longitudinal movement thereof relative to the vehicle as during a collision initiates fracture of the frangible pin which fracture is followed by movement of the retaining lever into a position wherein it is engageable with the striker to prevent movement of the hood member toward the raised position thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
In a vehicle including a body member having a closure member mounted thereon for swinging movement relative to said body member about a generally horizontal axis between a raised and a normal lowered position, a striker rigidly secured to one of said members, a retaining lever, means mounting said retaining lever on the other of said members for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said closure member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, frangible means rigidly connecting said retaining lever and said other member and maintaining said retaining lever in said first position thereof, and means operative upon longitudinal movement of said closure member from the normal lowered position thereof relative to said body member to fracture said frangible means and to pivot said retaining lever about said pivot axis thereof from said first to said second position so that swinging movement of said closure member toward said raised position iS prevented.
Claim 2
Dependent Claim
188 words
In a vehicle including a body member having a closure member mounted thereon for swinging movement relative to said body member about a generally horizontal axis between a raised and a normal lowered position, a striker rigidly secured to one of said members, a retaining lever, means mounting said retaining lever on the other of said members for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said closure member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, frangible means rigidly connecting said retaining lever and said other member and maintaining said retaining lever in said first position thereof, and means operative upon longitudinal movement of said closure member from the normal lowered position thereof relative to said body member to fracture said frangible means and to pivot said retaining lever about said pivot axis thereof from said first to said second position so that swinging movement of said closure member toward said raised position iS prevented.
Claim 3
Dependent Claim
188 words
In a vehicle including a body member having a hood member mounted thereon for swinging movement relative to said body member about a generally horizontal axis between a raised and a normal lowered position, a striker rigidly secured to one of said members, a retaining lever, means mounting said retaining lever on the other of said members for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said closure member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, spring means biasing said retaining lever toward said second position, and means operative upon longitudinal movement of said hood member from the normal lowered position thereof relative to said body member to fracture said frangible means, said spring means operative upon fracture of said frangible means to pivot said retaining lever about said pivot axis thereof from said first to said second position thereof so that swinging movement of said closure member toward said raised position thereof is prevented.
Claim 4
Dependent Claim
188 words
In a vehicle including a body member having a hood member mounted thereon for swinging movement relative to said body member about a generally horizontal axis between a raised and a normal lowered position, a striker rigidly secured to one of said members, a retaining lever, means mounting said retaining lever on the other of said members for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said closure member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, spring means biasing said retaining lever toward said second position, and means operative upon longitudinal movement of said hood member from the normal lowered position thereof relative to said body member to fracture said frangible means, said spring means operative upon fracture of said frangible means to pivot said retaining lever about said pivot axis thereof from said first to said second position thereof so that swinging movement of said closure member toward said raised position thereof is prevented.
Claim 5
Dependent Claim
241 words
In a vehicle body, a hood member, means mounting said hood member generally at the forward marginal edge thereof on said body for swinging movement relative thereto between a raised and a normal lowered position about a generally horizontal axis, a striker rigidly secured to said hood member generally at the rear marginal edge thereof, a retaining lever including a cam edge, means mounting said retaining lever on said body for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said hood member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, spring means biasing said retaining lever toward said second position thereof, and a frangible pin rigidly connecting said body and said retaining lever and maintaining the latter in said first position thereof, said striker in the normal lowered position of said hood member being positioned adjacent said cam edge and operative upon rearward longitudinal movement of said hood member from the normal lowered position thereof relative to said body to engage said cam edge and fracture said frangible pin and said spring means operative upon such fracture to pivot said retaining lever about said pivot axis thereof from said first to said second position so that swinging movement of said hood member toward said raised position thereof is prevented.
Claim 6
Dependent Claim
241 words
In a vehicle body, a hood member, means mounting said hood member generally at the forward marginal edge thereof on said body for swinging movement relative thereto between a raised and a normal lowered position about a generally horizontal axis, a striker rigidly secured to said hood member generally at the rear marginal edge thereof, a retaining lever including a cam edge, means mounting said retaining lever on said body for pivotal movement about an axis thereof between a first position wherein said retaining lever and said striker are freely relatively moveable permitting upward movement of said hood member from the normal lowered position thereof and a second position wherein said retaining lever and said striker are engageable to prevent such movement, spring means biasing said retaining lever toward said second position thereof, and a frangible pin rigidly connecting said body and said retaining lever and maintaining the latter in said first position thereof, said striker in the normal lowered position of said hood member being positioned adjacent said cam edge and operative upon rearward longitudinal movement of said hood member from the normal lowered position thereof relative to said body to engage said cam edge and fracture said frangible pin and said spring means operative upon such fracture to pivot said retaining lever about said pivot axis thereof from said first to said second position so that swinging movement of said hood member toward said raised position thereof is prevented.
