Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
An automobile front body structure having an engine compartment defined therein, and also having a pair of spaced first longitudinal frames extending beneath the engine compartment in a direction longitudinally of an automobile and connected at a rear end to a floor panel, which structure comprises: suspension arm support members secured to front ends of the first longitudinal frames, respectively, for the support of left-hand and right hand suspension arms; a transverse connecting member extending between the first longitudinal frames in a direction widthwise of the automobile and having its opposite ends connected to the respective support members; and said support members being of a generally T-shaped configuration having a body, secured to the front end of the first longitudinal frames, respectively, and a transverse arm detachably connected with an adjacent end of the transverse connecting member.
Claim 2
Dependent Claim
137 words
An automobile front body structure having an engine compartment defined therein, and also having a pair of spaced first longitudinal frames extending beneath the engine compartment in a direction longitudinally of an automobile and connected at a rear end to a floor panel, which structure comprises: suspension arm support members secured to front ends of the first longitudinal frames, respectively, for the support of left-hand and right hand suspension arms; a transverse connecting member extending between the first longitudinal frames in a direction widthwise of the automobile and having its opposite ends connected to the respective support members; and said support members being of a generally T-shaped configuration having a body, secured to the front end of the first longitudinal frames, respectively, and a transverse arm detachably connected with an adjacent end of the transverse connecting member.
Claim 3
Dependent Claim
79 words
The structure as claimed in claim 1, further comprising a pair of spaced second longitudinal frames extending above the respective first longitudinal frames in a direction longitudinally of the automobile and connected at rear portions to a lower region of a dash panel, a front cross member positioned frontwardly of the transverse connecting member and having its opposite ends secured to respective front ends of the second longitudinal frames, and a bracing member for each second longitudinal frame, said
Claim 4
Dependent Claim
85 words
The structure as claimed in claim 1, wherein each of the suspension arms is comprised of a wheel carrier end for the support of a front wheel, and a pair of arm portions forked from the wheel carrier end, said arm portions being resiliently displaceably connected to the associated support member through a bearing member and to a laterally outwardly protruding flange of the associated first longitudinal frame through a bearing member whereby the respective suspension arm is pivotable in a direction up and down.
Claim 5
Dependent Claim
107 words
The structure as claimed in claim 1, wherein at least the arm portion of each of the support members has a pair of opposite, downwardly extending flanges so shaped as to render the respective arm portion to have cross-section generally similar in shape to the inverted shape of a figure "U", and wherein said transverse connecting member is comprised of a channel bar and a flat bar joined together to render the transverse connecting member to have a generally closed hollow, each end of the transverse connecting member being received from below into the respective arm portion and then connected thereto by the use of fastening means.
