## Abstract

The present invention refers to a bullet- and blast-resistant window, in particular for use in a motor vehicle, which comprises a ballistic block having a peripheral face and a plurality of panes of glass, ceramic or plastic material bonded to each other over their surfaces in a layered composite, and interposed bonding interlayers of plastic material or adhesive, wherein an edge groove having slopes at least partly inclined for engagement with a part of the vehicle body and extending on and along at least a part of the peripheral edge of the window.

## Claims

### Claim 1

Bullet- and blast-resistant window, in particular for use in a motor vehicle, comprising a ballistic block having a peripheral face and a plurality of panes of glass, ceramic or plastic material bonded to each other over their surfaces in a layered composite, and interposed bonding interlayers of plastic material or adhesive, characterized by an edge groove having slopes at least partly inclined for engagement with a part of the vehicle body and extending on and along at least a part of the peripheral edge of the window,
wherein the ballistic block comprises a v-shaped block groove with oblique side walls and the window comprises a layer or insert made of bullet resistant material and bonded on at least one of the oblique side walls of the block groove,
wherein the oblique side walls of the ballistic block comprise an outer side wall and an inner side wall directed obliquely to an outside surface and an inside surface of the window of the vehicle, and the bullet resistant insert covers at least a part of the inner side wall of the V-shaped block groove.

### Claim 2 (depends on 1)

Bullet- and blast-resistant window according to claim 1, wherein the V-shaped edge groove has slopes with same or different inclination.

### Claim 3 (depends on 1)

Bullet- and blast-resistant window according to claim 1, further comprising an additional outer pane made of glass, ceramic or plastic material and bonded to an outside of the ballistic block by an interposing layer made of plastic material, the additional outer glass pane projecting over the peripheral face of the ballistic block on the peripheral edge of the bullet-resistant window.

### Claim 4 (depends on 1)

Bullet- and blast-resistant window according to claim 1, wherein the bullet-resistant insert is a strip made of ballistic steel.

### Claim 5 (depends on 1)

Bullet- and blast-resistant window according to claim 1, further comprising:
an inside surface recess provided on the inside surface of the window, wherein the inside surface recess adjoins the block groove on the peripheral face of the ballistic block; and
a bullet resistant part extending from the peripheral face of the ballistic block in the inside surface recess.

### Claim 6 (depends on 5)

Bullet- and blast-resistant window according to claim 5, wherein the inside surface of the window and the bullet resistant part are flush.

### Claim 7 (depends on 5)

Bullet- and blast-resistant window according to claim 5, wherein the bullet resistant part covers and/or overlaps the edge groove and the block groove of the ballistic block laterally.

### Claim 8 (depends on 5)

Bullet- and blast-resistant window according to claim 5, wherein the bullet-resistant insert and the bullet resistant part are connected to each other or are integral.

### Claim 9 (depends on 5)

Bullet- and blast-resistant window according to claim 5, wherein the bullet-resistant insert and/or the bullet resistant part is fixed on the ballistic block by an adhesive or polyurethane (PU) or polyvinylbutyral (PVB).

### Claim 10 (depends on 1)

Bullet- and blast-resistant apparatus for an automotive vehicle, comprising:
a bullet- and blast-resistant window according to claim 1; and
a bullet-resistant armoring device provided to be engaged in an edge groove having side walls at least partly inclined, and being part of the vehicle body.

### Claim 11 (depends on 10)

Bullet- and blast-resistant apparatus according to claim 10, wherein the armoring device covers an edge surface of the bullet- and blast-resistant window.

### Claim 12 (depends on 10)

Bullet- and blast-resistant apparatus according to claim 10, wherein the bullet-resistant armoring device fits positively into the edge groove of the window.

### Claim 13

A bullet- and blast-resistant window for a motor vehicle, comprising:
a ballistic block having a peripheral face and comprising:
a plurality of panes of glass, ceramic or plastic material; and
interposed bonding interlayers of plastic material or adhesive, wherein the plurality of panes are bonded to each other in a layered composite by the interposed bonding interlayers; and
an edge groove having slopes inclined for engagement with a part of a vehicle body of the motor vehicle, the edge groove extending on and along at least a part of a peripheral edge of the window,
wherein
the ballistic block comprises a V-shaped block groove with oblique side walls,
the window further comprises a bullet resistant insert of bullet resistant material and bonded on at least one of the oblique side walls of the V-shaped block groove,
the oblique side walls of the V-shaped block groove comprise
an outer side wall directed obliquely to an outside surface of the window, and
an inner side wall directed obliquely to an inside surface of the window, and
the bullet resistant insert is bonded on and covers at least a part of the inner side wall of the V-shaped block groove.

### Claim 14 (depends on 13)
